FreeBSD basebsd10 10.0-RELEASE FreeBSD 10.0-RELEASE #0 r260789: Thu Jan 16 22:34:59 UTC 2014     root@snap.freebsd.org:/usr/obj/usr/src/sys/GENERIC  amd64
>Description:
When attempting to boot FreeBSD 10 when we try to mount an export that is not currently available the boot process stalls at [tcp] 192.168.1.2:/x: RPCPROG_NFS: RPC: Program not registered and loops until the export becomes available.

fstab(5) documentation mentions:

"If the option ``failok'' is specified, the system will ignore any error
which happens during the mount of that filesystem, which would otherwise
cause the system to drop into single user mode.
"

My expectation is if we set failok we should ignore the RPC error and continue to boot.

root@basebsd10:/var/log # cat /etc/fstab
# Device        Mountpoint      FStype  Options Dump    Pass#
/dev/da0p2      /               ufs     rw      1       1
/dev/da0p3      none            swap    sw      0       0
192.168.1.2:/x/x       /mnt/x       nfs     rw,failok       0       0

>How-To-Repeat:
Point /etc/fstab to an export that is not available and boot the machine.
