When I mount an NFS volume, but I do not use an absolute path to the mountpoint,I can not umount the NFS mount:

mount_nfs shivav4:/export/pkgsrc test

Filesystem             512-blocks     Used     Avail Capacity  Mounted on
/dev/wd0a                50892140  4308344  44039188     8%    /

umount test
umount: /usr/john/test: not currently mounted

grittykitty: {11} umount /usr/john/test
umount: /usr/john/test: not currently mounted

rmdir test
rmdir: test: Device busy

mount_nfs shivav4:/export/raq /usr/john/test2
umount test2
