Author: smh Date: Sun Dec 21 17:21:29 2014 New Revision: 276027 URL: https://svnweb.freebsd.org/changeset/base/276027 Log: Switch zfsboot installer force 4K option to use vfs.zfs.min_auto_ashift=12 Previously we used gnop(8) to fake 4K sector size disks but ZFS now has a sysctl to control this when creating new top level vdev's so use that instead.
