If you can find an OS API that supports it, there's nothing preventing their use. For that matter, I once worked with a System III that would happily allow root to replace . and .. (this predated mkdir/rmdir Unix APIs) and, while fsck would complain, it "worked". You could create (and, thankfully, repair) such things as root with /etc/link and /etc/unlink. -- brandon s allbery kf8nh sine nomine associates [email protected] [email protected] unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
