Giving the mountpoint as argument to umount(8) fails with error "not a directory or special device" since a regular file is mounted there. Giving the host:/file as argument to umount(8) always fails with "/mount/point: Device busy". >How-To-Repeat: put a file or -alldirs into server's exportlist start mountd on server with option -r on the client: mkdir /tmp/mntfile mount -t nfs server:/exported/file/on/server /tmp/mntfile Now try unmounting it! >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
