well, yeah, it would probably best to handle this via wrapper. (like
for example mtx-changer script) as then only such a wrapper needs to
be modified for specific systems.
Under GNU/Linux at least there is sfdisk(8), and one can easily do a
partition dump with "sfdisk -d /dev/sda > somefile" and restore it
with "sfdisk /dev/sda < somefile".
If there was such a wrapper, each distribution could tailor it to its
own needs to allow (majority of) its users to have a hassle-free
out-of-the-box working environment.

That is, it is not that hard to do it, but it is hard to do it
automatically -- the cause of problem being exactly high portability
of bacula to different environments.
