nfsroot: Default mount option should ask for built-in NFS version
Change the nfsroot default mount option to ask for NFSv2 only *if* the kernel was built with NFSv2 support. If not, default to NFSv3 or as last choice to NFSv4, depending on actual kernel config. Signed-off-by: Helge Deller <deller@gmx.de> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
