Description

Randomly, the baremetal machines in NUE-FC-B 2 (https://racktables.nue.suse.com/index.php?page=rack&rack_id=19178) don't receive nameservers from DHCP. They receive IP address, default route, and even DNS search domains, but /etc/resolv.conf does not contain nameserver-entries.
It seems to (at least) affect all machines in this rack, not sure about others. Also restarting wicked manually ususally resolves the issue.
