   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ I'm an occasional

For LINBO, we probably don't need to change anything in Skolelinux.
LINBO consists of a kernel and an initial ramdisk für PXE booting a
graphical imaging and direct boot console that handles various operating
systems. It can be installed on any machine acting as DHCP-Server.

Only if we want to install LINBO on Tjener in order to easily
install and repair workstations in the same subnet, we could provide
scripts that change the DHCP servers configuration. But I believe this
can also be done manually. LINBO really just needs the two files in a
new directory that should be accessible for tftpd.

italc-rlp uses the same mecahnism and packaging as italc. So, this is
probably also no big deal, though the key installation mechanism could
be more elaborated.

Creating a Debian package for the LINBO binaries with documentation and
examples is easy. Creating a single source package from the 1.2 GB of
sources is near to impossible. I don't know if this is a requirement.
We have LINBO packages on http://rp.skolelinux.de/packages/linbo/, and
italc-rlp at http://rp.skolelinux.de/packages/italc/ .

Wait... One thing missing in LINBO is automatic localisation yet, since
it is quite monolithic, but this is not difficult to change.

Since the original italc in Debian is kind of abandoned and italc2 is,
as far as I know, not near to be usable, we made a fork of italc that
contains our addons, which are examination mode and observer
notifications plus a "loose interface" with cipux for internet access
and examinee account management. Our package contains the necessary
Conflicts: fields in order to just replace italc by italc-rpl cleanly,
and works fine with Skolelinux as well as plain Debian. We also have a
source patch of italc-rlp vs. italc, so it's quite easy to create
italc-rlp from italc using a diff.

Martin Öhler who has been working on italc-rlp and its packaging, has
discussed the issues with the italc authors, but these now seem to be
busy developing italc2, which is not useful as development base for us
right now.

We have an add-on CD containing LINBO and italc-rlp, which we use for
school installation.

Me, too. It would be great if some people who have the power to make it
happen, could attend our developer meeting in February in
Zweibrücken/Germany. More about this later.
