Thanks to both posters, but I decided against using the native mount type.
In part I wanted a bit of practice with Augeas and as Christopher wrote,
remounting is not safe.
Well, I stuck with my module and ended up with something that is not the
prettiest piece of code, but does the trick. No auto-remounts though!
define glusterfs::mount (
$server = "",
$volume = "",
$peers = "",
$mountpoint = "/mnt/gluster",
$dump = "0",
$pass = "0",
$description = "GlusterFS mount",
)
{
