Subtle: when creating symlinks, do NOT include $(DESTDIR) as part of
the source of the link. Otherwise when installing an MFS with something like DESTDIR=/mnt, you wind up with links like: lrwxr-xr-x 1 root wheel 25 Nov 9 11:45 lib@ -> /mnt/usr/local/etc/emulab which do not resolve when the MFS is booted. This assumes that DESTDIR is only used for temporary mounting of filesystems that are normally mounted elsewhere (and I believe that has always been the intent of DESTDIR, at least in BSD). If DESTDIR reflected the true path, then the links will now be wrong.
