Description danny 2009-10-05 09:10:02 UTC 
	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])

Fix: 

Fixed by the commit that modified pxeboot to use NFSv3 instead
	of NFSv2. (r212716 and r212717 to stable/8)
Comment 1 danny 2009-10-05 17:17:48 UTC 
the fix is to set boot.nfsroot.options="nfsv2" in /boot/loader.conf or  
via dhcp.
