Make installworld (as an integral part of make world) *does* touch a
permissions, since it uses mtree to generate directory structure. Therefore,
mtree will change permissions of /dev as well as others dirs listed in its
specs if they doesn't match with the specs. I've stuck in this feature several
times when making installworld on machine with /tmp from other machine mounted
over NFS into /mnt - as a result /tmp on the other machine lost its magic 1777
and received 755 instead. For quite some time I was curious why did it happen
until found a correlation between these two events.
