Delivered-To: submit@bugs.debian.org

Package: general
Version: 20010110
Severity: low

Sorry for not specifying the category more precisely.

I use several Debian 2.2s, with kernel module loading (i.e. no kerneld).
Some systems has 'cron' others use 'anacron'.
I found, that there is no crontab entry that removes unused modules
from memory. However I remember in 2.1 cron ran "rmmod -a" every
five minutes.
(Yes, I can fix this on my own hosts. ;-)

Regards

Gabor

This is not a bug, it is a deliberate choice. The problem with "rmmod -a"
is that:
1. it spins up the disk on laptops, which is unwanted
2. it can tickle a race in the kernel related to module unloading, which
   is really uwanted
3. not unloading modules generally doesn't hurt you at all
