Yes, my rpool is mirrored.
pool: rpool
state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not support
the features. See zpool-features(5) for details.

In 10_linux_zfs, there is an if statement that echos data:
if [ -n "${initrd_list}" -a -n "${kernel_list}" ]; then
echo
"${dataset}\t${is_zsys}\t${machine_id}\t${pretty_name}\t${last_used}\t${initrd_device}\t${initrd_list}\t${kernel_list}\t${last_booted_kernel}"
else
grub_warn "didn't find any valid initrd or kernel."
fi
The problem is that execution time, the last 3 parameters are dropped
even though they have data.

You can see from the expanded debug of the run (set -xv) that both
initrd_list and kernel_list had data that included the kernel and initrd
but within the if, it gets dropped. That is causing the generated
grub.cfg.new to be missing the kernel, initrd, and the advanced submenu
items that would normally be generated.
