There isn't a great deal of information, I'm afraid - it's something
that we started using years ago for metadata for d-i media. The
current contents of the directory (as used on 12.0.0 installation
media) looks like:
.disk/
base_components - lists the components in the image
that base-installer should look for
base_installable - a flag file - if present, all the packages for
the base system are in the image
cd_type - used by apt-setup to work out the type of image
(and the set it came from), so it can DTRT in terms
of asking about a mirror, etc.
id/<UUID> - a unique (empty) file, used to allow grub to find
the correct disk safely when it boots
info - human-readable information about the image,
generated by the build. This should be clear
and descriptive.
mkisofs - contains the complete command line used to
generate the ISO image, so people can reproduce/rebuild
it later
udeb_include - (optionally) lists udebs that should be installed by
default
udeb_exclude - (optionally) lists udebs that should *not* be installed
by default
Current live images include most of these, which is good - that helps
d-i to use the media too! However, as noted the info file is missing
some of the data people might expect. Current amd64 netinst says:
Debian GNU/Linux 12.0.0 "Bookworm" - Official amd64 NETINST with firmware
20230610-10:21
while the current gnome live iso says:
Debian GNU/Linux 12 "Bookworm" - Official Snapshot amd64 LIVE/INSTALL Binary
20230610-08:51
In the older bullseye live images, we used to have:
Official Debian GNU/Linux Live 11.7.0 gnome 2023-04-29T16:30
It would be nice to be able to tweak this in live-build, to contain
more information:
* Full version number
* image type / desktop
