Because JHT is a bit overboard here...
The problem is that not all tdbs need to be backed up - indeed, the tdbs
described as the problem here (connections/messages/sessionid in
particular) should in fact be deleted at startup.
The tdb that *must* be backed up is probably winbindd_idmap.tdb, given
the drastic consequences of loosing that file.
tdbbackup is reasonably new tool, and I'm sure patches to the init
scripts will be gratefully accepted.
