Subject: Re: [LTP] [PATCH V2 2/2] setpgid03: use SIGUSR1 instead of sleep

Hi!

I've overlooked the second case, however checkpoint works for this one
as well. You need to build a helper binary setpgid03_child.c that would
call the signal function and then do the wait.

The checkpoint interface is build on the top of unix sockets so it does
not matter whether the process was forked, execed or started from
termial. All that is needed is correct CWD (which is inherited both on
fork and exec) so that the socked special file is found.
