Here is the new version, so the folder tested is changed ;)
There is also a function called "check_mount_cgroup_options" which checks if 
the variable "mount_cgroups_at_startup" is yes, and if so, it will mount 
cgroups when starting the daemon, but it will also umount cgroups when 
stopping it. If the mount fails we exit, but we don't if it's the umount that 
fails.
