No. Obsolete files are left lying about on the hard drive. Usually
there are very few files that drop out between updates, so this isn't
a massive problem. It can be significant if you start playing with
the NO_FOO options in /etc/make.conf or for a major version upgrade.

If you go through a {build,install}world cycle and you don't use the
'-C' flag for install (set in /etc/make.conf), then all the files you
install will have timestamps within a few seconds of each other. You
can then identify the files that haven't been modified using find,
eg. for the root partition:
find -x / -mtime +1 -ls \( -name modules.old -o -name etc -o -name dev \) -prune
but you're going to have to go through that list manually to work out
which files are actually surplus to requirements.
Cheers,
Matthew
