From: Chuck Lever Date: Tue, 11 Sep 2007 18:01:04 -0400 NFS: Add new 'mountaddr=' mount option I got the 'mounthost=' option wrong - it shouldn't look for an address value, but rather a hostname value. However, the in-kernel mount client and NFS client cannot resolve a hostname by themselves; they rely on user-land to pass in the resolved address. Create a new mount option that does take an address so that the mount program's address can be passed in. The mount hostname is now ignored by the kernel.
