freebsd/usr.sbin/mergemaster/mergemaster.sh
Gordon Tetlow 55a5ff0140 Add auto upgrade capability to mergemaster. 
An mtree description of all non-zero files that make
distribution installs (only size and md5) is built from the
temproot.  When the user completes a mergemaster run, the
mtree description file gets installed into /var/db for
safe-keeping.

When the user then decides to do a subsequent upgrade (with
the -U flag), the existing mtree description from /var/db
is called into service looking for files that are different in
DESTDIR. This is stashed away until a file that would normally
end up prompting the user to look at changes is encountered.
Since there are no user modified changes, the new file is
installed without bothering the user.
