 Why should that block the reboot? All the process should use
 "/amd/server/what/ever/serverfilesystem" and not "/home" anyway.

 Backing out that change is not an option. I've added it because
 I frequently had problems with unmounting filesystem on my server
 during a shutdown or reboot.
 This happened because the amd(8) process got terminated but the
 pseudo NFS mounts were still active. The kernel tried to unmount
 them but didn't succeed because the NFS request didn't get handled.
