Subject: [PATCH] network/dhclient-script: set FQDN
|
|
|
|
When booting with nfsroot, dracut doesn't necessarily set the initial
|
|
hostname correctly.
|
|
|
|
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".
