I looked into this when I wanted to do this for DragonFly (but I got
sidetracked). There are few methods in the tree (at least in DragonFly,
I don't think it's completely different in FreeBSD) by which files get
installed:
- mtree
- ${INSTALL}
- ln
- zic (needs more work)
there might be some other things as well, but that's the major part by
which about 98% of all files are being covered.
This means, after converting all occurences of `ln' to ${LN} (done in
DragonFly, tho there are some things you can overlook) and `mtree' to
${MTREE}, ${INSTALL}, ${LN} and ${MTREE} can be replaced by wrapper
scripts which parse the parameters and record the created files into
some kind of log.
Storing these logs in, let's say /var/db/basefiles, let's you find out
files which were removed just by looking if a file doesn't appear in
the last log anymore.
I have to agree that wrapping the commands is a bit hackish, but it
basically works. Oh, of course this system also needs a static list of
files that were removed previously, so that it can bootstrap (it can
only catch files that were removed since the last time you ran
install-with-file-logging).
cheers
