Well, it depends. If you know, that you will access the SQLite database only 
from one host (start digikam only on one host) then it isn't a problem. In 
this case I would recommend to set the nfs option "nolock". In this case the 
lock isn't distributed to the nfs server and works reliable. The lock is only 
set on the local system.

We have big oracle databases ( > 1TB ) running on nfs in our company. Oracle 
uses locking on the data files. Oracle recommends to use the nolock option.
