Mount hangsEdit

ReasonsEdit
- Lockd is not running on the NFS server
- Portmap (older) or rpcbind (newer) is not running on the NFS client
- Networking is broken (e.g. scripts brought up default route but not IP address yet)
SolutionEdit
Two options are possible:
- run lockd on the server
- mount with nolock option
