Module Name: src Committed By: brad Date: Sun Sep 15 19:38:09 UTC 2019
Modified Files: src/distrib/sets/lists/base: mi src/distrib/sets/lists/etc: mi src/distrib/sets/lists/man: mi src/etc/defaults: rc.conf src/etc/rc.d: Makefile mountall src/external/cddl/osnet/dist/cmd/zfs: zfs_main.c src/external/cddl/osnet/sbin/zfs: Makefile Added Files: src/etc/rc.d: zfs src/external/cddl/osnet/sbin/zfs: mount_zfs.8 Log Message: Add support for legacy ZFS filesystems, specified by mountpoint=legacy in the ZFS properties of the dataset and a simple man page for mount_zfs. With this, it is possible to put ZFS filesystems in /etc/fstab as file system type zfs. Add a rc.d script that kicks the module ZFS load mostly before mountall runs simular to what LVM does. This allows for any legacy mounts to be specified in critical_local_filesystems and allows for ZFS pools on top of cgd (probably among other things). Introduce a rc.conf variable called zfs which needs to be set to YES, in the usual manor of things, to get zvols and ZFS dataset support rather then just assume that 'zfs mount' does that in mountall. Fix a problem in mountall if ZFS is not compiled into the system.
