validate: check if domain grain is set

[jschmid1]

Signed-off-by: Joshua Schmid jschmid@suse.de

If a user misconfigured their fqdn like so:

# hostname --fqdn
target-00

salt can't determine the domain

In [2]: 'target-00'.partition('.')[::2]                                         
Out[2]: ('target-00', '')

And we fail here

with:

Exception: According to the 'domain' grain, the cluster does not have a DNS domain configured

This is probably too late. Also the error message is not very descriptive.

My concern is that we break existing (working) installations that don't use SSL (yet).

Maybe raising a warning instead of an error is also fine?
