Dang.  That's too bad.  I'd kind of like to be able to use isconf
instead of the in-house system I'm using now (basically, systemimager's
updateclient + cvsup to overlay configurations), but we use the "reset
the system back to known baseline" functionality a lot.

=46rom reading more, it also seems like isconf assumes that your
environment never changes?  At least, there doesn't seem to be any way
to "collapse" the journal into a new base image so that you don't have
to replay the whole thing every time you image a new host.  In my case,
our current images are 2+ years old (Debian sarge), and there have been
a lot of things done to them in that period; having to replay 2 years of
changes (security patching apache multiple times, etc) every time I want
to install another rack of hosts doesn't seem like a good idea,
especially if someone removes a CNAME that hasn't been used for two
years but an early step in the journal depends on.
