It would be worth checking to see if the package manager has any intrinsic 
support for this kind of thing; FWIW I don't know that the ones that we use do 
(at least, we have no out-of-the-box integration for such functionality - I 
know some package managers have "delay until end" functionality for things 
like ldconfig and man page indexes, but we don't currently support this as far 
as I know).

One approach (untested) that could work now however would be to define a 
postinstall script for the package that would start another script in the 
background or via cron; the latter script would then wait until the package 
manager finished and then do whatever was necessary to restart the machine.

Cheers,
Paul
