Subject: [patch] 2.4.0: lp superuser check
Date: Fri, 5 Jan 2001 17:16:32 +0000	[thread overview]
Message-ID: <20010105171632.N5253@redhat.com> (raw)

Here is a patch that changes the superuser check in lp to use
capabilities instead.

Does anyone see a problem with it before I send it to Linus?

Tim.
