[PATCH] ZFS root in 10_kfreebsd.in

[PATCH] ZFS root in 10_kfreebsd.in

[Robert Millan]

[-- Attachment #1: Type: text/plain, Size: 178 bytes --]

This adds support for ZFS root in 10_kfreebsd.in.  It works with
current trunk if my grub-mkrelpath patch has been applied, and if
ZFS from grub-extras has been built into GRUB.

	* util/grub.d/10_kfreebsd.in: Initialize ${kfreebsd_device} as the
	kFreeBSD device name, except on ZFS where the filesystem label is
	used.
	(kfreebsd_entry): On ZFS root, load `opensolaris.ko', `zfs.ko' and
	`/boot/zfs/zpool.cache'.
	Set mountfrom kernel variable using ${kfreebsd_device}.
