I have a "file" /usr/include/linux which is misbehaving: $ ls -l /usr/include/linux c--sr-sr-t 1 26736 25601 46, 111 May 11 1999 /usr/include/linux I can't remove it or change permissions, either using sudo or a direct login as root. Get "permission denied" and "can't unlink". It's *supposed* to be either a directory, or a symlink to one. This isn't either a directory or a symlink. Any ideas about how I can axe the thing, given that root can't seem to chmod or delet it? This is a redhat 7.0 system, upgraded from 6.2 via the 7.0 beta (6.9). I suspect that the file was put there as part of the kernel-headers-2.4.?? by that beta install. Thanks, Andy
