Dear maintainer & reporter,
As Chris Dos indicated, the second part of this bug (missing pool after
`ZFS=`)
can be worked around by using `zdb` or `zpool` instead of `grub-probe`
to read
the pool name. This allows one to boot from a pool with unsupported
features, using a separate `/boot` partition).
The patch that they linked should fix this part of the problem, and
allow
`update-grub2` to run fine on such systems. Personally, I've been
using
this line in `/etc/grub.d/10_linux` as a workaround :
rpool=`zdb -l ${GRUB_DEVICE} 2>/dev/null | grep '\sname\:' | awk
-F"'" '{print $2}'`
In the case that both solutions are inadapted, I think that the script
should
provide a default value for `rpool`, such as `rpool`, as there is no
way
for the pool name to be empty.
Regards;
HG
