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
If root creates a file within a user's file hierarchy, the file is owned
by root but the directory containing the file is still owned by the
user. The user can still rename the file since the file name is in the
directory. Likewise, the file can be renamed. About the only thing the
user can't do is change the file contents.
Cheers,
Dave
