ZoL can create more zvols at runtime than can be configured during system start, which hangs the init stack at reboot. When a slow system has more than a few hundred zvols, udev will fork bomb during system start and spend too much time in device detection routines, so upstart kills it. The zfs_inhibit_dev option allows an affected system to be rescued by skipping /dev/zd* creation and thereby avoiding the udev overload. All zvols are made inaccessible if this option is set, but the `zfs destroy` and `zfs send` commands still work, and ZFS filesystems can be mounted.

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
