Ubuntu systems add this information to the motd:
[jk at pororo ~]$ ssh localhost
Linux pororo 2.6.32-23-generic #37-Ubuntu SMP Fri Jun 11 08:03:28 UTC
2010 x86_64 GNU/Linux
Ubuntu 10.04 LTS
Welcome to Ubuntu!
* Documentation: https://help.ubuntu.com/
0 packages can be updated.
0 updates are security updates.
[jk at pororo ~]$
The '0 packages..' data is added by a cron script, which essentially
does a:
/usr/lib/update-notifier/apt_check.py --human-readable
This script is provided by the update-notifier-common package, but I
have a feeling this may be Ubuntu specific. It just uses the python
apt_pkg library to grab the number of updates, so should be fairly easy
to adapt to what you want to do.
Cheers,
Jeremy
