[Openais] [call for porters to test corosync]

[Steven Dake]

Wojtek,

I've done a bit more work on portability.  I ran your install test case
and found the directories required by corosync are not present in
default csw.  Corosync doesn't warn the user and proceeds without
actually being functional.

Note the requirement for the ais user is now gone.  If you want to run
clients as user AIS, (or yourself) You can create ais user support by
adding a uidgid.d directory to your etc/corosync directory.  In that
dir, place a file called 

"ais" with contents
uidgid {
	uid: ais
	gid: ais
}

Finally if suing to root from a normal user, this apparently doesn't
promote your privileges enough for the getpeerucred() syscall.  Instead
you must do su - root

I ran 1 million cpgverifys single node and that appears to work.
cpgbench also works although alarm() has an odd behavior of resetting
the alarm signal handler to the default.

I'd be interested in your cpgbench numbers and logsysbench numbers.

All code is currently in trunk.

regards
-steve
