fc6 user...basic fs question.
Suppose I am root/UID 0. Is there a way to create a file in someone
else's (non-uid-0) FS hierarchy and have it be immutable? No rename, etc.?
I'm trying to do a hot-plug of disk keys and I would like to put some of
my own bytes somewhere so I know whether or not I've seen the disk key
before.
Some years ago I used SGI machines and they had a file system with a
volume header I could use. I don't think extX has such a capability.
I'm pretty sure the answer is no, but I figured I'd ask anyway.
Thanks,
John
