Should I be able to use mergemaster with freebsd-update?

Hi all,

In case anybody was following this discussion, I have successfully upgraded 
the system from 8.2 to 8.4 using freebsd-update. The process did have some 
glitches (in retrospect, minor ones) but mostly they were not related to 
freebsd-update (like some issues with gmirror and firewall configurations). 
The data merging phase was quite bearable and reasonable (if a bit tedious) 
and all the databases got properly updated.

Thanks to everyone involved!

IMHO it is partially broken; I'm not doing anything special. How broken it 
depends on what's getting changed. Most of what the system is designed to 
it indeed does very well. It also overlaps some of the functionality of
mergemaster in that it automatically merges as many files as it can, which 

Where it is under-designed and under-implemented is in its rudimentary
handling of un-mergeable files, and in its total lack of support for the
regeneration of /etc/*.db files (like the, uh, rather important password
database) and sendmail aliases - things that you would handle via 
in an ordinary, source-based upgrade, but which you must now figure out how 
do by hand, without any guidance, and they really don't make it easy for
