Which segfaults would those be? I use mysql replication and add users
all the time without any issues. I did this running both vpopmail 5.2.1
and 5.4.0-rc2. I've not yet added a domain under 5.4.0-rc2 but it worked
fine under 5.2.1, the only issue being that I manually had to add it to
the appropriate qmail files on each cluster server, though this is
automatable if I wished to do so.

Is there a reason that the mysql libs are statically rather than
dynamically linked? The bulk of the bloat comes from compiling in all of
that functionality.
