Hi Kunal.

This is triggered by uci validation as specified in
/lib/uci/schema/default/fstab .

Below is a simple patch to relax this check:

You could also edit the datatype check functions of the validator itself
by modifying the uvl/datatypes.lua class. Below is an oversimplified
example:

I hope this clears things up.
