Re: Pre-seeding XFree settings for keyboard in Debian Installer
-BEGIN PGP SIGNED MESSAGE-

Ok, I have now finished the infrastructure using version maps, but
before I upload I would like to describe the process, for feedback,
comments etc.
Basically the dir structure is this:
/conffiles.d:
sarge/ woody/ xfree86-kbd.preinst ispell.preinst ispell.postinst
ktouch.postinst kde2.postinst links.postinst
./conffiles.d/sarge:
xfree86-kbd
./conffiles.d/woody:
ispell ktouch xfree86-kbd kde2 links
You might notice that ispell has both preinst and postinst scripts,
this is because skolelinux/woody uses postinstallation configuration,
while ispell in sarge, can be preconfigured using debconf preseeding.
And the process:
update-locale-config is called, if a flag -p is given, then it
executes the .preinst scripts in conffiles.d, otherwise it executes
the .postinst scripts in the same folder. This is to ensure that we
can use configuration in pre- and post- stages of installation.
Each *.{pre,post}inst script has a version map that it uses to decide
which version it should run. I have separated the common routines in
common.pl, and use this to get the appropriate version. Here is a
small part of the conffiles.d/xfree86-kbd.preinst:
-
require 'common.pl';
getopts("dlp", \%opts);
init();
my %xvermap = ( '4.1.0-1', => { RELEASE => 'woody' },
'4.3.0-1', => { RELEASE => 'sarge' }
);
my $script = "xfree86-kbd";
my $package = "xserver-xfree86";
my $release = get_release($package, %xvermap);
$script = "$release/".$script;
print "Running $script $lang\n";
system ($script, $lang) if -x $script;
- --
Basically, I wanted it small and clean, so that it would be easy to
create new ones. The xvermap array holds the versions and release
names. I just put the minimum versions in which the configuration is
different (4.3.0 introduced some slight differences in XkbOptions).
I then execute the $release/$script file, which is the same script as
it was in locale-config-skolelinux. I prefered this approach as I
really like modularity and dislike huge scripts with lots of if
clauses :-)
If for some reason, an older/newer version has no available method for
{pre,post}-configuration then the script can just be a dummy script
(a link to /bin/true perhaps?).
How does get_release() then works?
If the package exists AND is installed then i compare the currently
installed version to the version map. If it is not installed then I
check -using apt availability list- againsg the latest version.
If the package does not exist or something went wrong with other
methods, I fallback to checking /etc/debian_version (though that
should not happen often).
That's about it, I will have uploaded the package later this day at
http://people.debian.org/~markos/debian/

True, but this applies for everything, and maintaining will be easy for older releases, only the latest will actually need active maintenance... Anyway, I attach the update-locale-config script as I've changed it so far. I am no perl expert, so if you find anything that needs tidying up, feel free to correct it. I haven't uploaded anything to the skolelinux cvs, and I think that would be a bad idea anyway, I don't want to break anything in skolelinux right now.

Most of them would be hard to map to the proper script. We gave up collecting and using the information after seeing how different the values actually were. Yes, we might just as well dropp it.

There is no reason why it should not work, after all, I can just add a
new option for the next release. Right now, I keep a map with
possible values in debian_version and corresponding script folders,
like that:
my %supported_versions = ( 'woody' => { FOLDER => 'woody' },
'sarge' => { FOLDER => 'sarge' },
'testing/unstable' => { FOLDER => 'sarge' }
);
if in the future we have another release, we could just add one more
entry. Of course if it's a matter of the folder names, sure I could
change these.

unpredictable ways? I don't really understand what you mean. It *is*
there for a reason, if it is not actually usable, then we might just
as well, drop it! :-)

Yup, too bad that aspell has no such support... I'll tell you when I
have something to test...

Well, from what little I've seen, it appears that dictionaries-common
is supposed to configure ispell itself. So if we pre-seed
dictionaries-common... :-)

This do not work. We tried collecting that info in popularity-contest, and it is often changed in unpredictable ways. We have been unable to find a sure way to detect which version/codename of debian is installed. I'm not sure how it is best to handle this, but suspect the scripts need to change behaviour depending on the version of packages installed, not depending on the debian codename being used. > In the meantime, since the current ispell configuration is > debconf-based, I will make one extra script for sarge > ispell.preinst.

Ok, here is what i have now:
conffiles.d/:
sarge woody
conffiles.d/sarge:
ispell.preinst xfree86-kbd.preinst
conffiles.d/woody:
ispell.postinst ktouch.postinst locale.preinstopera6.postinst
xfree86-kbd.preinst kde2.postinstlinks.postinst
ltsp-xfree86-kbd.? timezone.postinst
I have also updated the update-locale-config script to take one more
parameter {preinst/postinst} so that it can be called in two separate
times, one at the start (runnint the preinst scripts) and one at the
end running the postinst scripts.
It will read the /etc/debian_version and accordingly run the
appropriate scripts from the correct directory.

In the meantime, since the current ispell configuration is
debconf-based, I will make one extra script for sarge ispell.preinst.
Also, now that I think about it, there is a new infrastructure for
dictionaries, dictionaries-common that configures the appropriate
ispell dictionary from a list. So perhaps I should just pre-seed
dictionaries-common instead?

Good. for me at least yes but the timezone setup is quite simple for Greece, with only one option, I don't know if it works as it should with more complex locale configs(eg.

Ok, basically i'm creating a list of configuration to be executed before installation of packages, and another one at the end of the installation. (in reality, there will be 2 such pairs, one for woody and one for sarge). Will keep you posted. Konstantinos

You don't need to split the package in two. You can have one package, with two base-config fragments. I do not think it will be possible to get all packages configurable with debconf in a reasonable time frame, so I believe we need to keep both ways of configuration.

Konstantinos can you give details about > this? Ok, I started tidying up the package, basically it doesn't really need much tidying up (Petter has done a good job :-), but here are my comments: * package has been renamed to localization-config as discussed with Petter in debconf. * of all the conffiles.d, we only need xfree86-kbd, and probably kde(but updated for kde 3) * ispell needs to be updated to new versions which are (I think) debconf base * maybe add gnome configurations (but I have very little gnome experience) * we don't really need locale and timezone (as these are handled by debian-installer) * we also don't need to configure links and ktouch (as these are optional packages and not debconf based), ltsp-xfree86-kbd (as it's skolelinux specific) and opera6 (not available in debian itself) * If we decide to update kde as well, then we have to either: a) make kde configurable by debconf, or b) split the package into 2 subpackages, one to be called before X configuration (thus pre-seeding debconf values) and one after (finishing up KDE configuration). I don't really like any of these solutions, but I would go for one I'd go for the first. As it is, KDE 3 does quite a good job of detecting the default locale after a first installation (there is only a problem with the default X dpi and fonts resolution), but I only tested this for Greek. So, perhaps we could just skip KDE configuring as well. So that leaves us with just XFree86 and (possibly) ispell preseeding. Thoughts? Konstantinos

Konstantinos Margaritis is working on packaging the debian-edu tool to do this. It is currently called locale-config-skolelinux, but will probably be renamed before it is uploaded.
