Debian-edu installation override files
======================================

This package overrides all Debian debconf questions to make sure the
Debian-edu CD can be installed non-interactively.

More info is available from <URL:http://wiki.debian.org/DebianEdu/>.

Extracting debconf values from d-i after installation
-----------------------------------------------------

apt-get install debconf-utils
debconf-get-selections --installer

How to update the partman partition rules
=========================================

The partition recipes are in lib/partman/common/.  there are files for
each combination of valid profile choises. the recipe file is built
from the common file, and the arch specific file.  to create the
correct recipe file for arch and profile choice.

The recipe consist of min, priority, max size and the file system
type, as well as information about the file system to create.  An
example: The min and max sizes are min MiB.

  32 2000 10000000 ext3
	$lvmok{ }
	method{ format }
	format{ }
	use_filesystem{ }
	filesystem{ ext3 }
	mountpoint{ /debianedufreespace } .

The format is documented in
http://anonscm.debian.org/gitweb/?p=d-i/debian-installer.git;a=blob;f=doc/devel/partman-auto-recipe.txt .
The code using the recipes is in d-i subversion,
packages/packages/partman/partman-auto/reciepes.sh.

It is a good idea to make sure there is at least 20% free space on
every partition, to avoid warnings from nagios about too full
partitions in a freshly installed system.  5% is reserved for root,
and the remaining 10% is the number nagios is checking, and partman
some times create partitions smaller than the minimum size, so add 10%
extra to reduce the chance of problems caused by this.  So, if 652 MiB
is used on /usr, the partition should be at least (652 * 100 / 70) =
932 MiB.  It is a good idea to round up to the closest 64 MiB to take
into account the overhead in file systems and LVM.

One thing to keep in mind is that /var/ is used as storage area for
downloaded debian packages during installation of the netinst CD, and
thus need a lot more disk space during installation than after
installation.

To learn about the disk requirement for individual recipes, run the
command 'make minimum-diskreq'.

Some numbers to keep in mind.  All numbers are disk space used in MiB,
collected just after installation.

Testing translations
====================

To test if the line wrapping work with translations, a command
like this can be used:

  COLUMNS=77 podebconf-display-po debian/po/it.po

It will simulate the terminal width available in the text mode
of debian-installer.
