fstabs I use (and have been using for a really long time) usually look
somewhat like this:

,----
| LABEL=ds-md-root        /               ext4    errors=remount-ro 0       1
| LABEL=ds-md-usr /usr            ext4    noatime         0       2
| UUID=0858f078-5222-4002-91ae-c452ec4b6a0e       none    swap    sw      0       0
| LABEL=ds-md-sysdata     /sysdata           ext4    defaults        0       2
| LABEL=ds-md-home        /home           ext4    defaults        0       2
| 
| /sysdata/var    /var    ext4    bind    0       0
| /sysdata/tmp    /tmp    ext4    bind    0       0

It's also pretty obvious that the lines must be processed in order
because mounted filesystems can contain future mountpoints, eg, for a
'classic' example, mount some network filessystem as /usr and a local
one as /usr/local.
