I said:
I've just done the upgrade on one VPS. I came
across two issues.
I've now done another one. This time, dovecot went ok (perhaps because I
had copied the certificates ahead of time), but it uninstalled MySQL
rather than upgrading it from 5.1 to 5.5 - just mysql-common was upgraded.
As the previous upgrade also said that 5.1 was going to be removed, I
didn't notice that 5.5 wasn't in the install list. Fortunately, that
this had happened was obvious on restarting. My guess is that it's down
to how it was installed in the first place, possibly as version 5.0 or
5.1 rather than as the generic package.
If I've missed anything, do let me know.
Memory is telling me that in the change from Lenny to Sqeeze, the
correct file ownership of BIND's slave zone files in /var/cache/bind/
changed - syslog would get lots of..
named[2067]: zone
example.com/IN: refresh: could not set file
modification time of '/var/cache/bind/example.com.hosts': permission denied
.. messages until the ownership was changed.
It's possible it's changed again (back to what it was?) because the
messages came back. After..
chown bind:bind /var/cache/bind/*
.. everything looks happy.
