Hi Robert,

The NIS or icecc can't work when task network is dissable, add BB_TASK_NETWORK
to enable network globally for such exceptions.
Note, enable nscd on the build machine might be a solution, but that isn't
reliable since it depends on whether the network function has been cached or
not.

You can return ASAP instead of iterating over all users:
with open('/etc/passwd', 'r') as f:
for line in f.readlines():
if not ':' in line:
continue
if line.split(':')[2] == uid:
return True
return False
Otherwise, since we explicitly add icecc functions to existing tasks,
can't you just add [network] = "1" to all those tasks in icecc.bbclass?
e.g. do_configure[network] = "1" ?
Also, even if icecc is globally inherited and enabled, recipes can still
disable its use on a per-recipe basis in which case I don't think we
should have the network enabled?
I can't comment on NIS support.
Cheers,
Quentin
