I've thought about it before, and posted my thoughts on the devel list, on
a thread called 'bconsole restore bug - option 12', starting here...
http://marc.info/?l=bacula-devel&m=125302334920002&w=2
...and continue to worry about it.

I still think that getting rid of bacula's dependence on clocks, and having
a 'this job depends on jobid x' field would fix a host of problems.

I can see that maintaining continuity with, or migrating from previous bacula
versions would be difficult. But I think the move would be best in the long
term.
