Most of this hinges on the --upload option being passed, and it never is any more. Much of it also uses Google Buckets, which we no longer use, save for some GCE-specific bits. Signed-off-by: James Le Cuirot <jlecuirot@microsoft.com>

# This uses Gentoo's catalyst for very thoroughly building images from scratch.
|
|
# For reference the procedure it performs is this:
|
|
#
|
|
# 1. seed: Take a recent SDK, dev container, or custom tarball as a seed to
|
|
# build stage 1 with. Before proceeding, update relevant packages that have
|
|
# changed sub-slot to avoid missing library issues later in the build.
|
|
#
|
|
# 2. stage1: Using the above 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.
|
|
# NOTE that stage1 LACKS PROPER STAGE ISOLATION. Binaries produced in stage1
|
|
# will be linked against the SEED SDK libraries, NOT against libraries built
|
|
# in stage 1.
|
|
#
|
|
# 3. stage2: This is skipped as recommended by upstream Gentoo.
|
|
#
|
|
# 4. stage3: Run emerge -e system to rebuild everything 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 stage3 etc]
|
|
# By default all four stages will be built using the latest stage4 as a seed.
