Yep.  That's from testing...yaird doesn't come into play until 2.6.14.

I booted to knoppix and:

    # mount /mnt/hda1
    # chroot /mnt/hda1
    # mount /proc

When I tried to uninstall/install anything I would get 'permission denied'
errors in regards to '/dev/null'.  This causes (I think) the postinstall
scripts to fail and the packages aren't configured.

I looked at dpkg(1) especially the --force options but couldn't find
anything to help.

any ideas?

Thanks again,

Jon
