--- Comment #3 from Ngie Cooper <ngie@FreeBSD.org> ---
(In reply to Edward Tomasz Napierala from comment #2)

Sure.

Oy.. this is amusing:

$ touch /tmp/uchg.file
$ chflags uchg /tmp/uchg.file
$ rm -f /tmp/uchg.file
rm: /tmp/uchg.file: Operation not permitted
$ sudo rm -f /tmp/uchg.file
$ rm /tmp/uchg.file
rm: /tmp/uchg.file: No such file or directory

This means that the test will at the very least need to be run by an
unprivileged user... but why can root always remove the file..? Hmm..
