Author: rnoland Date: Mon Dec 7 16:37:02 2009 New Revision: 200220 URL: http://svn.freebsd.org/changeset/base/200220 Log: MFC 199714 Create a seperate ZFS enabled loader. This adds zfsloader which will be called by zfsboot/gptzfsboot code rather than the tradional loader. This eliminates the need to set the LOADER_ZFS_SUPPORT variable in order to get a ZFS enabled loader. Note however, that you must reinstall your bootcode (zfsboot/gptzfsboot) in order for the boot process to use the new loader. New installations will no longer be required to build a ZFS enabled loader for a working ZFS boot system. Installing zfsboot/gptzfsboot is sufficient for acknowledging the use of CDDL code and therefore the ZFS enabled loader.
