Proposal:

• 00* - 1100_prepare-build-machine
• 01* - Qubes only, nothing Whonix specific
• 02* - Qubes only, nothing Whonix specific
• (virtual) 03* - Qubes only, nothing Whonix specific
• 04* - take 02_install_groups_pre.sh and rename it to 04_install_qubes_post.sh (all inside chroot: creates packages, installs packages, run the chroot scripts)
• 09* - 09_cleanup_post.sh

Would that be better?

Still non-ideal. Ideally, packages would be build outside the chroot so the build dependencies do not get installed inside the image. Combining the two build systems in a non-hacky, non-complex way seems difficult. Would it be better if qubes-builder would build all the Whonix packages? I wonder if that could be done without a giant components.conf listing all the packages git repos. And without adding a Makefile.builder to each and every Whonix package.

Perhaps #makefile-generic-packages (genmkfile) could be extended to implement all make targets, that qubes-builder requires.

Yes, exactly.

Whonix uses submodules for all the components, right? So it can be
considered a single component to qubes-builder, which produces a lot of
packages. Are some Whonix-specific steps required to build the
components, or generic dpkg-buildpackage is enough? In case of the
later, it would be enough to place single Makefile.builder in main
Whonix repository which lists all the components in DEBIAN_BUILD_DIRS
(list can be easily generated based on submodules list, or some script
output). Note that the order is important to satisfy build depends. If
something more than dpkg-buildpackage is required, it may be enough to
place it in SOURCE_COPY_IN step, or some more flexible mechanism
should be designed.

This would mean that it isn’t possible to build a single Whonix package, only all of them. If that’s a big issue, we could either introduce some qubes-builder mechanism to build a single package of multi-package component (IMO preferred, useful not only here), or consider each Whonix package as a separate components (as you’ve noted, not ideal).

Ok.

I don’t think this is an issue.

Looks like I’ll be working on the 02 to 04 transition now. Required for other purposes. My experiments show, that this use of apt-get in 09_cleanup_post.sh does not work. (No proper chroot anymore at that stage?)

If qubes-builder-debian provides 04_install_qubes.sh, then qubes-template-whonix cannot provide an additionally executed 04_install_qubes.sh, right? At least, that seems so in my experiments. Is this a bug or feature?

That would also mean, that likely qubes-builder-debian and qubes-template-whonix’s 09_cleanup_post.sh would also conflict, i.e. only qubes-builder-debian one would run.

- build Whonix in 04_ instead of 02_ as suggested by @marmarek - https://phabricator.whonix.org/T402
- removed many hacks

This is done.
