Components are ordered “main contrib non-free” almost everywhere, let's
use the standard order here too. There should be no functional changes.
Note: This controls the sources.list file used during the build, but
doesn't control “deb cdrom:” lines in sources.list during or after
installation, which are the result of running apt-cdrom (which sorts
components alphabetically, see its pkgCdrom::ReduceSourcelist function).
When local packages are enabled (LOCAL=1), various things happen in the
target /dists directory. One of them is the creation of a /dists/local
symlink, pointing to (/dists/)<CODENAME>. This leads to a very confusing
situation, where “local” is initially about a component, but effectively
ends up looking like a distribution.
It is theoretically possible that cleaning this up might require some
follow-up fixes in other tools, but even that would be better than
keeping bear traps around.
It's possible to set LOCAL=1 to enable support for local packages, which
automatically results in “local” being listed in /.disk/base_components,
which is used to build the --components parameter for debootstrap.
Users might have various sets of *.deb and/or *.udebs, be it over time,
or for various codenames, and it's possible for /dists/<CODENAME>/local
to be entirely missing in the generated image.
In this case, /.disk/base_components must not contain “local”, as that
would break debootstrap; this commit detects and fixes this possible
inconsistency.
This is a regression introduced while trying to catch up with apt's
expectations, in 2183089968c04c4765d2119d176e021431b26353: iterating over
Packages files is done by running the “zcat” utility on Packages.gz and
Packages.xz; replacing Packages.gz with an uncompressed Packages broke
iterating over Packages files referencing udebs.
This might have worked by accident depending on the exact layout under the
LOCALDEBS directory (see previous commit for the big picture).
Let's focus on where input files for d-i should be stored:
<LOCALDEBS>/dists/<CODENAME>/local/debian-installer/binary-amd64/*.udeb
Those *.udeb end up being stored under the “local” component[1] (making it
clear they're not from usual components on a Debian mirror), but they are
referenced in Packages for the “main” component[2], possibly replacing a
different version found in the archive.
/dists/<CODENAME>/local/debian-installer/binary-<ARCH>/*.udeb [1]
/dists/<CODENAME>/main/debian-installer/binary-<ARCH>/Packages [2]
This makes it possible for d-i to find those *.udeb automatically, as it
uses a single Packages file.
Mimic what make_disc_trees.pl does, making it possible for hw-detect to
spot not only the /firmware/dep11 directory in netinst images, but also
on installation images with firmware added manually.
Rename pseudo-option to clarify it returns filenames and indices.
Keep generation disabled for bullseye (as an extra safeguard, even if we
have separate, per-release branches anyway): That's helpful information
but bullseye is a stable release, and changing even unofficial material
might not be the best idea. Be cautious by default, it's easy enough to
enable if desired.
The next step for make-firmware-image is to use generate_firmware_patterns
for each firmware package that was detected. That command requires DEP-11
metadata, so needs to know which Packages file each firmware package comes
from.
Instead of building long $pkgfiles and $bp_pkgfiles strings, and passing
them to catz, build lists instead and iterate over them. This means a few
more catz calls, but that also means being able to derive the DEP-11
directory from Packages paths.
There should be no functional changes.
Since that tool might be used without a caller that sources CONF.sh,
be explicit about the components in which firmware packages must be
searched:
- use "main contrib non-free" for bullseye;
- use "main non-free non-free-firmware" for bookworm and above.
non-free can go away once we have all we need in non-free-firmware.
Export some environment variables for generate_firmware_task (also
renaming SUITE to CODENAME).
Treat the output file argument specifically when it's “--list-filenames”:
instead of actually generating a task file with a list of packages (and a
few comments), output the Filename field for each firmware package
matching our criteria.
Move some status messages to STDERR accordingly.
This makes the “find suitable firmware packages” reusable, e.g. by
make-firmware-image.
