I've Googled for this and found where someone else has seen this but no explanation.
#ls -l mh
lrwxrwxrwx 1 root root 1 Dec 25 2002 mh -> .
Any explanation of this?
It came up during a tar of /usr where it appeared to go into a loop, backing up /usr/bin under /usr/bin/mh, then under /usr/bin/mh/mh ....
After I noticed that about 10 levels of mh were scrolling on the screen I killed it then removed the link.
Is this link a bug or is there some reason for it to be there?
