File 0206-nfs_dns_alias.patch of Package dracut.7257

From: Fabian Vogt <fvogt@suse.com>
Subject: NFS: Support host being a DNS ALIAS

The "host" command may also print something else than
"asdf.local.lan has address 1.2.3.4", like:
"rootserver.local.net is an alias for rainbow.local.net.".
So "head -n1" is not enough.

Fixes boo#955592
