Created attachment 535417 [details] Patch to dracut version of dhclient-script to set fqdn Description of problem: When booting with nfsroot, dracut doesn't necessarily set the initial hostname correctly. Version-Release number of selected component (if applicable): dracut-network-013-18.fc16 How reproducible: Always Steps to Reproduce: 1.On a dhcp server configure option host-name = short; option domain-name example.domain; 2. Boot client with systemd.unit=rescue.target 3. /bin/hostname Actual results: short Expected results: short.example.domain Additional info: According to dhcp-options(5), the name may or may not be qualified with the local domain. It goes on to say "it is preferable to use the domain-name option to specify the domain name". So dhclient-script needs to be able to handle the cases: a) where host-name is fully qualified and domain name is also specified; b) where hostname is fully qualified and the domain is not separately specified; c) where host-name is "short" and domain-name is also specified; and d) do its best where host-name is short but domain-name is not specified. The dhclient-script in initramfs does not handle case "c", apparently the preferred situation properly, setting hostname to "short". Patch attached.
