Mount order for directories

[Nick Pierpoint]

Hello all.

If I have a disk mounted on /opt:

	mount /dev/hdb1 /opt

but then also have another disk mounted on /opt/thensome

	mount /dev/hdb2 /opt/thensome

In /etc/fstab I'd have something like:

	LABEL=/opt          /opt           ext3 defaults 1 2
	LABEL=/opt/thensome /opt/thensome  ext3 defaults 1 2

My question is will this always work? When directory mounts have a
degree of inter-dependence how do you specify the mount order? Does the
mount process religiously follow through the order in fstab?

Many thanks.
