Brian Behlendorf 5e7affae52 Skip /dev/hpet during 'zpool import' 
If libblkid does not contain ZFS support, then 'zpool import' will scan
all block devices in /dev/ to determine which ones are components of a
ZFS filesystem.  It does this by opening all the devices and stat'ing
them to determine which ones are block devices.  If the device turns
out not to be a block device it is skipped.

Usually, this whole process is pretty harmless (although slow).  But
there are certain devices in /dev/ which must be handled in a very
specific way or your system may crash.  For example, if /dev/watchdog
is simply opened the watchdog timer will be started and your system
will panic when the timer expires.

It turns out the /dev/hpet causes similiar problems although only when
accessed under a virtual machine.  For some reason accessing /dev/hpet
causes qemu to crash.  To address this issue this commit adds /dev/hpet
to the device blacklist, it will be skipped solely based on its name.

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
