hard link problems

[xegan]

I have a hard link that mysteriously appeared on my root drive, and I can't remove it.

It is a hard link to "/". I have no idea how it got there. The link is named the same as my DNS/IP name at work (appeared at home - iBook). I tried various ways of removing it, but only ended up starting to wipe my Apps folder (started with the dot-files, then started working
down the alphabet - wiped 1/2 of my apps folder before I realized it. Careful with that "rm -R"!).
I've tried re-linking from root to an empty folder.

Everything I try says "operation not permitted".

A few iNodes have shown up and am wondering if their presence points to a corruption of the FS.
I tried to figure out any iNode problems, but "fsdb" wouldn't work on my system either.

fixed it.

cause: mounted network volume connected when I disconnected, causing some process to
get left behind, locking down the link... or something.??

fix: boot into single user mode, "mount -aw",
then a "ln -f filename".
