Subject: [PATCH] Add ``cloneconfig'' target
Date: Thu, 24 Feb 2011 21:35:02 -0500 [thread overview]
Message-ID: <4D671556.80607@suse.com> (raw)
Cloneconfig takes the first configuration it finds which appears
to belong to the running kernel, and configures the kernel sources
to match this configuration as closely as possible.
