Installs over ZFS where a ZFS disk is expected to be used as a root device.
- Run update-grub on a system with a ZFS root filesystem.
Installs relying on the current broken behavior to avoid listing other
operating systems in grub menu may find that new entries are added.
update-grub runs /usr/sbin/grub-probe
Without libzfslinux support compiled in, /usr/sbin/grub-probe runs
["zpool", "status", poolname] to find out ZFS info.
zpool responds with device names as used at (I think!) pool creation
time. Often, this is /dev/disk/by-id/... names, without the path.
grub-probe then parses the output, and takes the names of devices, and
if they do not start with a "/", it prepends "/dev/".
It then tests the existence of the path name of the device. it fails.
grub-probe then returns something like
/usr/sbin/grub-probe: error: failed to get canonical path of `/dev
The actual path is of course /dev/disk/by-
It can prepend smarter than "/dev" or it can understand ZFS natively,
to fix the problem.
