And with this feature, if I understood correctly, old kernel keeps on running after this type of reboot. If so, kernel modules loaded via /etc/rc.conf[.local] can cause version mismatch with running kernel, forcing single user mode. So I'd prefer making 'zboot' pool as real rootfs and mount needed datasets from main pool. (Use povot-root only for userland-only updates.) # Pivot-root would be similar to configuration below. Right? *Use UEFI loader of 10.3 or later *UFS having /boot *ZFS NOT having /boot (at least, /boot/loader.efi) */boot/loader.conf has vfs.root.mountfrom line pointing inside ZFS Below can be optional. *UFS is mounted to some mountpoint such as /ufsboot after boot *ZFS has symlink /boot pointing /ufsboot On Thu, 28 Apr 2016 20:39:51 +0900 Tomoaki AOKI <junchoon@dec.sakura.ne.jp> wrote: > Finished at r293744 (MFC of r290548), right? > > https://lists.freebsd.org/pipermail/svn-src-stable-10/2016-January/007753.html > > > On Thu, 28 Apr 2016 11:57:44 +0100 > Steven Hartland <killing@multiplay.co.uk> wrote: > > > I thought that was in 10.3 as well? > > > > > > On 28/04/2016 11:55, krad wrote: > > > I think the new pivotroot type stuff in 11 may help a lot with this > > > > > > https://www.freebsd.org/news/status/report-2015-10-2015-12.html#Root-Remount > > > > > > > > > > > > On 28 April 2016 at 10:31, Malcolm Herbert <mjch@mjch.net> wrote: > > > > > >> On Thu, Apr 28, 2016 at 12:44:28PM +0500, Eugene M.
