Oh dear. You really haven't grasped this have you?

   Clearly not ... enlighten me ......

1. Use fstab to PERMANTLY mount them at boot time before NFS even come up
2. use their partition UUIDs in fstab  to associate  each partition with a defined mount point.

   Hmmm ...
   Haven't used fstab for external USBs in a long time,
   but it's worth a TRY here. I'll use the _netdev option
   to help cope with any delays.

e.g.
 PARTUUID=0916c1e1-d006-4b19-9378-d687271d3612  /home               ext4    defau
lts,noatime  0       1
PARTUUID=aec7525a-1e13-4a52-a23f-d8a0d17f6da7  /home/Media ext4
  defaults,noatime  0       1
PARTUUID=778a9e44-03 /backup ext4    defaults,noatime  0       1
PARTUUID=778a9e44-06 /backup2 ext4    defaults,noatime  0       1
PARTUUID=778a9e44-05 /home/Media/Unedited ext4 defaults,noatime  0       1
 These are all USB connected SSD partitions. They are all exported by NFS without problems.

   Gimme a few hours and I'll report.
   Oh, I generally mount-by-label, not UUID, since the
   label TELLS you stuff.
