+# Example cross compile for x86_64, multilib-enabled
+# This can be adapted for different architectures, but do note that some
+#   architectures will need more recent versions of gcc/glibc/tools.
+# The version of gcc in /bootstrap should be able to build any such newer
+#   versions, at least as of right now (GCC 10.2).
+
+# To homogenize build instructions across both multilib and non-multilib
+#   installs, and because some applications require heavy patches to install 
+#   in alternate libdirs (cough cough python), the lib directory will contain
+#   native libraries, while lib32 whill contain 32-bit libraries.
+# GCC will be patched slightly, and configured to achieve this, as by default
+#   it uses lib64 and lib.
+
+# To initialize/enter chroot:
+# mkdir dev tmp
+# mknod dev/null c 1 3
+# ./bootstrap/bin/chroot . /bootstrap/bin/env -i NPROC="$(nproc)" /bootstrap/bin/sh /sources/build_cross.sh
+
+# Amount of make threads, configure this to your liking.
+# This can be obtained using `getconf _NPROCESSORS_ONLN`, but requires /proc
+#   to be mounted, which we avoid.

+Based on portage-3.0.8 and gentoo-20201031 snapshot
+
+The specifics of this document (software versions and whatnot) are subject to
+change as gentoo evolves, but I hope the big lines of it won't change too
+much.
+
+This guide starts off with a system built from build_cross.sh, built for
+x86_64 with i686 multilib.
+It might be possible to adapt both that script, and this guide for other
+architectures, but this guide won't go into detail.
+
+You should be running a system with a x86_64 kernel (with i686 support).
+Install the required sources (listed in gentoo.wget-list) into /sources.
+
+To enter the bootstrap system as a chroot, use the following commands to set
+up the filesystems and entering:
+mkdir -p proc sys dev tmp
+mount -t proc proc proc
+mount -t sysfs sysfs sys
+mount -t devtmpfs devtmpfs dev
+mount -t devpts devpts dev/pts
+mount -t tmpfs tmpfs dev/shm
+mkdir -p etc
+touch etc/resolv.conf
+mount --bind /etc/resolv.conf etc/resolv.conf
+./bootstrap/bin/chroot . /bootstrap/bin/env -i PATH=/bin:/sbin:/usr/bin:/usr/sbin:/bootstrap/bin:/bootstrap/sbin HOME=/root /bootstrap/bin/sh -l
+
+To install all the prerequisite tools, place the sources (listed in
+gentoo.wget-list) under /sources, then run the gentoo_tools.sh script.
+
+Configure portage:
+echo "root:x:0:0:root:/root:/bin/bash" > /etc/passwd
+echo "root:x:0:root" > /etc/group
+echo "portage:x:250:250:portage:/var/tmp/portage:/bin/false" >> /etc/passwd
+echo "portage::250:portage" >> /etc/group
+echo "C UTF-8" > /etc/locale.gen

+chmod 0700 /root
+cat > /etc/portage/make.conf << 'EOF'
+FEATURES='-pid-sandbox -news'
+ROOTPATH=/bootstrap/bin:/bootstrap/sbin
+EOF
+ln -sf ../../var/db/repos/gentoo/profiles/default/linux/amd64/17.1/ /etc/portage/make.profile
+
+Install ebuild repository (pick appropriate date, see distfiles.gentoo.org/snapshots):
+emerge-webrsync -v --revert=20201031
+
+Install some ebuild prerequisites:
+emerge -O1 sys-apps/gentoo-functions  # Used by elt-patches and a ton of other things
+emerge -O1 app-portage/elt-patches  # required by elibtoolize(libtool.eclass), used to install any library
+emerge -O1 sys-devel/gnuconfig  # required by gnuconfig_update(gnuconfig.eclass), used by toolchain(-glibc).eclass, doesn't hurt to have
+emerge -O1 sys-devel/binutils-config sys-devel/gcc-config
+
+First, we will build an updated binutils+gcc combo that targets /usr instead
+of /bootstrap. This makes it easier to bootstrap glibc and everything else. We
+will use portage for this, even though it's a mess.
+
+NOTE: Doing this is (probably) *BAAAAD*, since we're linking the compiler
+support libraries with a potentially incompatible version of glibc in
+/bootstrap, and upgrading it afterwards. Glibc should always be installed
+first into a new prefix! However, due to the complex relationship between
+glibc, gcc, libgcc and libstdc++, this is rather hard to do while wrangling
+the change from /bootstrap to /usr, as well as the multilib libdir changes, so
+for simplicity's sake, I won't bother. This just works™.
+
+Install temporary libc files for target compiler:
+mkdir -p /lib64 /lib
+ln -sf /bootstrap/lib/ld-linux-x86-64.so.2 /lib64/ld-linux-x86-64.so.2
+ln -sf /bootstrap/lib32/ld-linux.so.2 /lib/ld-linux.so.2
+mkdir -p /usr/include
+ln -sf /bootstrap/include/limits.h /usr/include/limits.h
+mkdir -p /usr/lib64 /usr/lib
+ln -sf /bootstrap/lib/{crti,crtn,Scrt1}.o \
+       /bootstrap/lib/{libc,libm,libpthread}.so /usr/lib64/
+ln -sf /bootstrap/lib32/{crti,crtn,Scrt1}.o \
+       /bootstrap/lib32/{libc,libm,libpthread}.so /usr/lib/
+
+Install binutils+GCC (linked against /bootstrap):
+USE='-*' emerge -O1 sys-devel/binutils
+USE='-* static-libs' EXTRA_ECONF=--disable-shared \
+    CPPFLAGS='-isystem/usr/include' LDFLAGS='-L/usr/lib64 -L/usr/lib' \
+    emerge -O1 dev-libs/gmp dev-libs/mpfr dev-libs/mpc
+USE='-*' EXTRA_ECONF=--disable-bootstrap GCC_MAKE_TARGET=all \
+    CPPFLAGS='-isystem/usr/include' LDFLAGS='-L/usr/lib64 -L/usr/lib' \
+    CPATH=/bootstrap/include \
+    emerge -O1 sys-devel/gcc
+emerge --rage-clean dev-libs/gmp dev-libs/mpfr dev-libs/mpc
+gcc-config 1  # Not automatic unlike binutils-config...
+
+NOTE: The Glibc ebuild downloads a file called gcc-multilib-bootstrap, which
+contains prebuilt binaries to bootstrap multilib gcc. This is _only_ used when
+the command "echo 'int main(){}' | $CC -m32 -xc -" fails, and shouldn't be
+being used in this bootstrap, but you can make sure of that by patching the
+ebuild to `die` instead of running the `sed` command to enable its use.
+
+NOTE: BOOTSTRAP_RAP=1 is only used in the Glibc ebuild, to avoid a pre-install
+check that might pick up programs from /bootstrap to test against the
+installed glibc, as well as picking up python from $PATH instead of
+eselect-python. I'm not aware of how the support status is for this variable,
+and as such it might disappear in the future, or be used in more packages.
+
+Install initial glibc:
+CC=/bootstrap/bin/gcc emerge -O1 sys-kernel/linux-headers
+USE='-*' BOOTSTRAP_RAP=1 emerge -O1 sys-libs/glibc
+
+NOTE: `sandbox` outputs a failure message to stderr for every program still
+built against /bootstrap, which includes the compiler. Some autoconf scripts
+check stderr to determine a failure, so this causes builds to fail. This is
+why it's (partially) disabled for this stage.
+
+Bootstrap the rest of the system:
+USE=-seccomp emerge -O1 app-misc/pax-utils
+cd /var/db/repos/gentoo/scripts
+mkdir -p /var/run
+ln -s /bootstrap/bin/python3 /usr/bin/python
+rm -f /etc/profile.env
+USE=-nls FEATURES=-usersandbox BOOTSTRAP_RAP=1 ./bootstrap.sh
+
+Reinitialize the environment:
+env-update
+exec bash -l
+export PATH=$PATH:/bootstrap/bin:/bootstrap/sbin
+
+In the following stages, you'll get tons of LD_PRELOAD libsandbox.so errors
+from programs still linked against /bootstrap. This is safe to ignore, and
+will gradually disappear as programs are rebuilt.
+
+It'd be nice to remove the bootstrap tools now, but among wget/openssl, gawk,
+gzip, grep, and other tools, they're still required for some reason.
+
+From this point onward, you're pretty much on your own to beat portage into
+performing an `emerge -e @system` and fixing any unspecified dependencies you
+encounter along the way. This can be done in a whole number of ways, and will
+differ on any given day, since this is painfully unsupported by gentoo devs.
+Because the order in which you install everything can differ wildly, and
+consequently affect the output of your build, it is advised to do a second
+`emerge -e @system` afterwards, for sanity. Below I detail my most recent
+procedure, which, I can't stress enough, may or may not work at the time
+you're reading this.
+
+Fix circular dependencies:
+USE=-filecaps emerge -O1 sys-libs/pam
+USE='-acl -xattr' emerge -O1 sys-apps/shadow  # required by acct-group/acct-user
+
+Verify there's no circular deps left, for sanity:
+emerge -fe @system
+
+Build everything:
+emerge -e @system
+
+Clean up bootstrap tools/configs:
+rm -rf /bootstrap /sources
+rm -f /etc/portage/make.conf
+
+Reinitialize environment:
+env-update
+exec bash -l
+
+Consider rebuilding everything again without /bootstrap, since a lot of
+packages couldn't be properly stripped, and a bunch of other tools have been
+upgraded, during the first emerge -e @system:
+emerge -be @system
+
+To install everything into a clean root:
+ROOT=/final emerge -K @system
+
+Prepare files for catalyst:
+mkdir -p /var/tmp/catalyst/snapshots
+wget -O gentoo-latest.tar.xz http://distfiles.gentoo.org/snapshots/gentoo-latest.tar.xz
+mkdir -p /var/tmp/catalyst/builds/default
+cd /var/tmp/catalyst/builds/default
+tar -C /final -cf stage3-amd64-latest.tar .
+xz -9v stage3-amd64-latest.tar
+rm -rf /final
+wget -O stage1.spec "https://gitweb.gentoo.org/proj/releng.git/plain/releases/specs/amd64/stage1.spec"
+wget -O stage2.spec "https://gitweb.gentoo.org/proj/releng.git/plain/releases/specs/amd64/stage2.spec"
+wget -O stage3.spec "https://gitweb.gentoo.org/proj/releng.git/plain/releases/specs/amd64/stage3.spec"
+sed -i -e 's/@TIMESTAMP@/latest/' -e '/^portage_confdir: /d' *.spec
+
+Build the stage3:
+emerge catalyst
+catalyst -f stage1.spec
+
+Clean up chroot:
+umount -R proc sys dev etc/resolv.conf

+rm -rf /var/db/pkg
+
+Install initial glibc:
+CC=gcc emerge -O1 sys-kernel/linux-headers
+mkdir -p /usr/bin/
+ln -sf /bootstrap/bin/python3 /usr/bin/python3tmp
+PYTHON_COMPAT_OVERRIDE=python3tmp emerge -O1 sys-libs/glibc
+rm -f /usr/bin/python3tmp
+
+This compiler and dynamic linker will now pick up everything correctly under
+/usr instead of /bootstrap:
+rm -f /etc/portage/bashrc /etc/portage/gcc.specs
+
+Build the remainder of bootstrap utilities:
+cd /var/db/repos/gentoo/scripts
+rm -f /etc/profile.env
+mkdir -p /var/run
+USE=-nls ./bootstrap.sh
+
+You'll get tons of LD_PRELOAD libsandbox.so errors from programs still linked
+against /bootstrap. This is fine to ignore, and will gradually disappear as
+programs are rebuilt.
+
+It'd be nice to remove the bootstrap tools now, but among wget/openssl, gawk,
+gzip, grep, and other tools, they're still required for some reason.
+
+From this point onward, you're pretty much on your own to beat portage into
+performing an `emerge -e @system` and fixing any unspecified dependencies you
+encounter along the way. This can be done in a whole number of ways, and will
+differ on any given day, since this is painfully unsupported by gentoo devs.
+Because the order in which you install everything can differ wildly, and
+consequently affect the output of your build, it is advised to do a second
+`emerge -e @system` afterwards, for sanity. Below I detail my most recent
+procedure, which, I can't stress enough, may or may not work at the time
+you're reading this.
+
+Fix circular dependencies:
+USE=-filecaps emerge -O1 sys-libs/pam
+USE='-acl -xattr' emerge -O1 sys-apps/shadow  # required by acct-group/acct-user
+
+Verify there's no circular deps left, for sanity:
+emerge -fe @system
+
+Build everything:
+emerge -be @system
+
+Clean up bootstrap tools/configs:
+rm -rf /bootstrap /sources
+rm -f /etc/portage/make.conf
+
+Reinitialize environment:
+env-update
+exec bash -l
+
+Consider rebuilding everything again without /bootstrap, as surely a lot
+errors popped up during the first emerge -be @system, can't be sure enough.
+
+To install everything into a clean root:
+ROOT=/final emerge -K @system
+
+Prepare files for catalyst:
+mkdir -p /var/tmp/catalyst/snapshots
+wget -O gentoo-latest.tar.xz http://distfiles.gentoo.org/snapshots/gentoo-latest.tar.xz
+mkdir -p /var/tmp/catalyst/builds/default
+cd /var/tmp/catalyst/builds/default
+tar -C /final -cf stage3-amd64-latest.tar .
+xz -9v stage3-amd64-latest.tar
+rm -rf /final
+wget -O stage1.spec "https://gitweb.gentoo.org/proj/releng.git/plain/releases/specs/amd64/stage1.spec"
+wget -O stage2.spec "https://gitweb.gentoo.org/proj/releng.git/plain/releases/specs/amd64/stage2.spec"

+sed -i -e 's/@TIMESTAMP@/latest/' -e '/^portage_confdir: /d' *.spec

+Current LFS version: 10.0
+
+Substantial changes were introduced in LFS 10.0, so these notes will probably
+not apply to anything below this version. This version should be easier to
+bootstrap like this, anyway.
+
+Ignore the Host System Requirements, a lot of these either don't apply or will
+be procured as we go through this guide.
+Ignore, as well, the creation of a new partition or user, as the necessary
+tools to achieve this aren't available in the bootstrap toolset. We will be
+building everything on whatever partition the bootstrap toolset was installed.
+
+Install the sources under /sources right next to the /bootstrap directory.
+This can't be done when inside the bootstrap system as no networking utilities
+are yet installed. For the "xz" package, download a .tar.gz or .tar.bz2
+package, as the xz utilities aren't included with the bootstrap utilities.
+
+To enter the bootstrap system as a chroot, use the following commands to set
+up the filesystems and entering:
+mkdir -p sys proc dev tmp
+mount -o ro -t devtmpfs devtmpfs dev
+mount -o ro -t devpts devpts dev/pts
+mount -o ro -t sysfs sysfs sys
+mount -o ro -t proc proc proc
+./bootstrap/bin/chroot . /bootstrap/bin/env -i PATH=/bootstrap/bin HOME=/root /bin/sh -l
+
+Set the LFS variable to either / or keep it blank, as the bootstrap tools are
+self-contained in /bootstrap, and can be removed afterwards, keeping a clean
+system anyway.
+
+The bootstrap tools are all x86, if you're going to be cross-compiling for
+x86_64, make sure the command `uname -m` returns `x86_64`, or manually
+substitute it throughout the LFS commands you execute.
+
+In chapter 4.4 Setting Up the Environment, make sure LFS is set according to
+what's been explained, and PATH=$LFS/tools/bin:/bootstrap/bin. We don't want
+to use /usr/bin and /bin until chapter 7. Also define LFS_TGT after setting PATH.
+Also `mkdir /root` before creating the files. If you don't want the "I have no
+name!" prompt, you shouldn't use '\u' in the PS1 variable.
+A finished bashrc/bash_profile looks like:
+mkdir -p /root
+cat > ~/.bash_profile << "EOF"
+exec env -i HOME=$HOME TERM=$TERM PS1='\w\$ ' /bin/bash
+EOF
+cat > ~/.bashrc << "EOF"
+set +h
+umask 022
+LFS=
+LC_ALL=POSIX
+PATH=$LFS/tools/bin:/bootstrap/bin
+LFS_TGT=$(uname -m)-lfs-linux-gnu
+export LFS LC_ALL LFS_TGT PATH
+EOF
+source ~/.bash_profile
+
+Once you get to chapter 5, you will need to add a couple of tools to the
+/bootstrap toolset, by building them from the sources you've downloaded for LFS.
+
+You'll need to build the following packages:
+- xz-5.2.5 (required to unpack .tar.xz archives)
+- sed-4.8 (required by linux-headers for -E option)
+- m4-1.4.18 (required by bison)
+- bison-3.7.1 (required by glibc)
+- grep-3.4 (required by glibc for -o option)
+- make-4.3 (required by glibc)
+- Python-3.8.5 (required by glibc)
+
+Install them by unpacking them (see "General Compilation Instructions" chapter),
+and running:
+./configure --prefix=/bootstrap --build=i686-pc-linux-gnu
+make
+make install
+
+Python with:
+./configure --prefix=/bootstrap --build=i686-pc-linux-gnu --without-ensurepip
+
+Now, you can run chapter 5 and 6, with the following exceptions:
+
+5.3. GCC-10.2.0 - Pass 1:
+    Add --with-stage1-libs='-lstdc++ -lsupc++' CC='gcc -std=c11'
+    to the ../configure command.
+
+6.3. Ncurses-6.2:
+    Use --disable-stripping during "main" ./configure
+
+6.4. Bash-5.0:
+    Do not move bash to /bin or replace the /bin/sh symlink. We'll do this
+    later.
+
+Once you reach chapter 7, run the finishing bash install commands we skipped earlier:
+mv $LFS/usr/bin/bash $LFS/bin/bash
+ln -sfv bash $LFS/bin/sh
+
+Now, if you're cross-building for x86_64, this is the point where you should
+make sure you're either already running a compatible kernel, or you reboot
+into one. You might be able to build one with the tools in /bootstrap and
+/tools, but this guide won't cover this. Booting into this system instead of
+chrooting will also require extra steps, not covered here.
+
+You may skip chapters 7.1 and 7.2, since we've built everything as root, and
+7.3 may be skipped as well as we've already set up the chroot. However, you
+should set up the PATH variable as described in chapter 7.4, by for example
+modifying your bashrc:
+cat > ~/.bash_profile << "EOF"
+exec env -i HOME=$HOME TERM=$TERM PS1='\u:\w\$ ' /bin/bash
+EOF
+cat > ~/.bashrc << "EOF"
+set +h
+umask 022
+PATH=/bin:/usr/bin:/sbin:/usr/sbin
+export PATH
+EOF
+source ~/.bash_profile
+
+Chapter 7.5 onwards can be followed without any modifications. This is all
+standard LFS stuff from here on.
+
+It's probably not related to this specific bootstrap, but I had to run the
+following extra commands during the remaining chapters:
+
+7.10. Perl-5.32.0:
+    Run the following command after sh Configure:
+    echo '#define MB_LEN_MAX 16' >> config.h
+
+7.13. Util-linux-2.36:
+    Run the following command after ./configure:
+    echo '#define SSIZE_MAX LONG_MAX' >> config.h
+
+8.15. M4-1.4.18:
+    Run the following command after ./configure:
+    echo '#define MB_LEN_MAX 16' >> lib/config.h

+mktemp is a peculiar phenomenon in the linux world.
+Well, I'm sure things like this happen more often, but,
+
+Turns out, there once was an mktemp.c written for OpenBSD.
+Distributions started including it, writing their own version, the usual.
+Apparently, popularity of this tool became big enough, and incompatibilities
+between versions arose significantly, that it was split off into its own
+package and website, https://www.mktemp.org, around 2000. Written by Todd C.
+Miller, the author of sudo!
+This version was included in Debian under the package name "debianutils", with
+the last known version being debianutils-2.8.4, where it was split into its
+own "mktemp" package, both reflecting the state of version 1.5.
+
+https://lists.gnu.org/archive/html/bug-coreutils/2007-10/msg00051.html
+In 2007, GNU coreutils adds its own, slightly incompatible version of mktemp
+with coreutils version 6.10.
+I can only assume most linux distributions switched to it, because come 2008,
+mktemp-1.6 releases, featuring GNU compatibility.
+Debian switches to coreutils inmediately, while Slackware keeps it for another
+decade, citing the incompatibilities, and installing the GNU version as
+mktemp-gnu, only reverting this decision in 2018.
+
+I could've sworn one of my scripts ran into the differences between mktemp-1.5
+and GNU mktemp, but I can't figure out what it was, and check for it, now.
