Puppet has a native module for handling fstab mounts. Here is an example:

class data_mounted {
    mount { "/data":
        device  => "/dev/sdb1",
        fstype  => "ext4",
	ensure  => "mounted",
	options => "defaults",
        atboot  => "true",
    }
}

The “device” directive can take anything what you’d normally put in the first column of /etc/fstab, i.e. if you are mounting by label (which is probably the best way to mount partitions) then instead of “/dev/sdb1” call for “LABEL=data”, where ls -l /dev/disk/by-label/data should point to the actual [and existing] partition, which in my case is /dev/sdb1.

The “fstype” is the actual type of the partition, if you are not sure of the type you can check it with df -T. You can mount linux ext partitions, nfs, samba, 9p etc.
