[Timo Savola]

The following commit has been merged in the upstream branch:
commit d7583168b40e4238252968be21d2e44b0fc42ea1
Author: Timo Savola <tsavola at movial.fi>
Date:   Sat May 21 08:41:48 2005 +0000

    Daemon support (TCP version)
    
    faked goes into "detached" mode when it receives SIGHUP: it will terminate
    as soon as all clients close their connections.  The fakeroot script kills
    faked with SIGHUP instead of SIGTERM when it exits.  This is done in order
    to provide a working (although isolated) fakeroot environment for daemon
    processes that are launched from a fakeroot session.
