Hmmm, I think this explains the initial problem I saw, after doing 
setup; cleanup; setup

The first setup will bump up the shmmax.
The cleanup will remove ovirt-engine.conf. However if you don't reboot, 
shmmax remains boosted.
The second setup will detect that shmmax is fine, and not create 
ovirt-engine.conf.

A subsequent reboot will revert shmmax to the default value, and 
postgresql will fail to come up.
