Unless you dual boot with Windows, I recommend running the BIOS clock
on UTC, not local time. Windows expect the BIOS clock to be local
time, and get confused if shutting down before summer time kick in and
boot after it kick in. Having the BIOS clock run on local time when
it is unable to understand the time zone settings lead to such
problems.

I am quite sure it is done at boot to, but worked around when ntp
start a
bit later in the boot. See the UTC setting in
/etc/default/rcS to control how Debian handle the BIOS clock. The
default is to believe the BIOS clock is running on UTC, which is my
recommondation to you.

No idea. autofs must be confused, somehow.
Hmm, I have done no changes to autofs whatsoever... the only changes to the filesystem that is done is that I removed the entry for backup in fstab,
and replaced it with a nfs share. But no changes to users home dir or anything else.
