Brian Behlendorf abe5b8fb66 Improve 'zpool import' EBUSY error message 
When a device is already open O_EXCL by another process the
`zpool import` will correctly fail.  However, the default failure
message isn't very helpful.  It may in fact be harmful if you
take its advise and destroy your pool.

    cannot import 'tank': pool is busy
            Destroy and re-create the pool from
            a backup source.

Improve the error message in the EBUSY case to simply print a
message indicating that the devices are current in use.  The user
will need to manually identify which process has the device open
exclusively and why.

README.markdown

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!

$ ./configure
$ make pkg
