# This uses Gentoo's catalyst for very thoroughly building images from
|
|
# scratch. Using images based on this will eliminate some of the hackery
|
|
# in make_chroot.sh for building up the sdk from a stock stage3 tarball.
|
|
#
|
|
# For reference the procedure it performs is this:
|
|
#
|
|
# 1. snapshot: Grab a snapshot of portage-stable. Note that overalys are
|
|
# not snapshotted.
|
|
# 2. stage1: Using a "seed" tarball as a build environment, build a
|
|
# minimal root file system into a clean directory using ROOT=...
|
|
# and USE=-* The restricted USE flags are key be small and avoid
|
|
# circular dependencies.
|
|
# 3. stage2: Run portage-stable/scripts/bootstrap.sh
|
|
# This rebuilds the toolchain. Probably not strictly necessary most of
|
|
# the time but does super-duper-promise that the toolchain isn't linked
|
|
# to or otherwise influenced by whatever was in the "seed" tarball.
|
|
# 4. stage3: Run emerge -e system to rebuild everything using the fresh
|
|
# toolchain using the normal USE flags provided by the profile. This
|
|
# will also pull in assorted base system packages that weren't included
|
|
# in the minimal environment stage1 created.
|
|
# 5. stage4: Install any extra packages or other desired tweaks. For the
|
|
# sdk we just install all the packages normally make_chroot.sh does.
|
|
#
|
|
# Usage: bootstrap_sdk [stage1 stage2 etc]
|
|
# By default all four stages will be built using the latest stage4 as a seed.
