If there are encryption keys, they have to be located somewhere, and if
they're on the disk that's stolen, then a thief might still have enough to
defeat the encryption. That's particularly possible if he knows enough about
your operations, or can cajole information from someone who does. If they
are on some other disk available to the server, the thief merely steals two
disks instead of one to obtain them.

Aother issue is that you can be denied access to the source. If an
untrusted person has root access, that person can simply destroy your
repository, encrypted or not. That's the point that some others have made
about root access. The attacker would not have your source, but you wouldn't
either.

Even without damaging the system, a rootkit or other malicious program could
do a lot of damage just by monitoring your server activity. That might be
very hard to discover.
