[Pacemaker] Notes on pacemaker installation on OmniOS

[Grüninger, Andreas (LGL Extern)]

I added heartbeat and corosync to have both available.
Personally I use pacemaker/corosync.

There is no need any more to run pacemaker as non-root with the newest version of pacemaker.

The main problems with pacemaker are the changes in the last months especially in services_linux.c.
As the name implies this must be a problem with non-linux systems.
What is your preferred way to handle e.g. pure linux kernel functions?

I compiled a version of pacemaker yesterday but with a revision of pacemaker from august.
There are pull requests waiting with patches for Solaris/Illumos.
I guess it would be better to add this patches from august and my patches from yesterday to the current master.
Following the patch from Vincenco I changed services_os_action_execute in services_linux.c and added for non-linux systems the synchronous wait with ppoll  which is available for Solaris/BSD/MacOS. Should be same functionality as this function uses file descriptors and signal handlers.
Can pull requests be rejected or redrawn?

Interesting work... a couple of questions...

- Why heartbeat and corosync?
- Why the need to run pacemaker as non-root?

Also, I really encourage the kinds of patches referenced in these instructions to bring them to the attention of upstream so that we can work on getting them merged.
