When running a NBD server, NBDSPEC is a comma separated list of
devices and partitions for the NBD servers starting at port 7525.
e.g. "lun0:part1,lun1:disc" corresponds to 2 NBD servers, one at port
7525 serving the first partition of chip #0, and the other at TCP
port 7526 serving the whole disc device of chip #1.
