For a manual mount, I agree.
But I think 'mount -a' should mount everything from /etc/fstab, unless 
it is already mounted.
I would suggest the same when mount is called with only one of 
filesystem and mountpoint and the other information is taken from 
/etc/fstab.
That way you can use something like 'mount /proc' as 'make sure /proc is 
mounted'.
