I've thrown together a quick mergemaster enhancement that will
automagically upgrade files that have changed in the /usr/src/etc
distribution but the user hasn't changed. Great applications are for
when you trust that we aren't going to break everything and only don't
want mergemaster to squash files that you have customized.
How it works:
Through clever use of mtree, I build an mtree description of everything
that make distribution installs (only size and md5) 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 you to look at
changes is encountered. Since there are no user modified changes, the
new file is installed without bothering the user.
Let me know what you think.
