[Gluster-users] /etc/init.d/glusterfs restart for CentOS

[Andrew McGill]

Having looked for it, and not found one, here's a glusterfs init script 
for CentOS/RHEL which I have slapped together with minimal testing.  It 
differs from the ones in 'extras' in the following ways:

  * Starts multiple servers named /etc/glusterfs/*server.vol
  * Mounts client shares listed with -o noauto in /etc/fstab
  * Works on RHAT, which doesn't provide /lib/init/vars.sh

There may be a better way of doing all this.
