Really? I've missed that completely.

I understand perfectly well what you did. But we've seen *a lot* of
cases before when moving one of these platform independent programs
(like mhonarc, which is written in perl IIRC) between Linux and FreeBSD
and get significantly different behaviour. Either in that it crashes, or
more often in that it gives different results without crashing. What you
did was move one of our core services from FreeBSD to Linux, which
potentially has a lot of effects. I'm not saying that something broke,
I'm just asking how much you actually verified.

AFAIK, we also had a bunch of customizations in mhonarc - did those get
migrated over, or are we now running a stock mhonarc?

Good, thanks!

Oh, and I also notice there has been zero commits about this to the
autobackup repository, so obviously none of this is included in said
backups - that also needs to be fixed.
