It seems only consequent to omit all settings specific to the network
interface: addresses, netmask, etc.  And if you do not set an IP
address, it does not make sense to set a netmask, right?

Hostname (set to generic board name) is in so far somewhat of an
exception as quite a lot of people appear to use this to organize
their TFTP download directories.

It is difficult to give simple rules for these things.  There is a lot
of habits and decade old traditions involved, so please don't ask me
for some formally defined rule sets.

Best regards,

Wolfgang Denk
