>Description:
	the initial diskless boot is still via nfs/v2, and once
	the kernel remounts it, it now fails with error 1001 (NFSERR_BADHANDLE),
	after some hacking in nfs_vfsops.c - dropping NFSMNT_NFSV3,
	I get error 70, which the netapp reports as:
	Client 132.65.82.135 (xid 1501470721) is trying to access an unexported mount (fileid 12829350, snapid 0, generation 0 and flags 0x0 on volume 0x8b847e [No volume name available])
