I had read the mergemaster man page previously, and used it. I just
read it again, and then looked at the -current source (I'm running 4.2
release with some stuff updated to RELENG_4). I can't see that it
does what I want - or could, given that it would need information that
I don't think is maintained anywhere.
Specifically, I'd like to see a scheme such that:
all mechanisms that put files in /etc (when those files are
automatically drived from src/etc somehow), should record
(e.g. md5 checksum in /var/db/etc.md5) the version of each file as
automatically installed. These mechanisms include
normal installs
normal upgrades
running mergemaster
running make install from src/etc
all these mechanisms also, when putting files in /etc, put the new
file in place if the old file doesn't exist or is recorded as being
unchanged (e.g. md5 matches database). Additionally, the database
is updated with the md5 of the file that should be installed, so
that copying those bits in resets the state to 'not locally
modified'.
I don't understand how to do this with mergemaster. In particular, I
don't understand how mergemaster could possibly know whether an
existing file is untouched from an older release or locally modified.
I also don't understand how to use mergemaster to accomplish /etc
updates without having a source tree when upgrading to a new binary
release (off CD or the net).
