Dunno whether this counts as pilot error or documentation deficiency.

What documentation are you using, can you provide the link (if it's the LE wiki it will need updating).    

 Sorry, can't remember off the top of my head, will have to search.
I said documentation because I followed some instructions for setting up system.d mounts rather than using smb:// for the media...
Will try to find 'em.  

Sorry Milhouse, I think I boobed in saying it was faulty documentation - it's pilot error + systemd changes.
I based my services on the cifs.sample in .config, but I chose to use /media/<xxx> for the mountpoints rather than /storage.
This was fine until systemd changed in one of the recent builds as HiassofT pointed out.
Anyway, all fine now :-}
