I'm quite new with submitting code like this. I asked questions about where

So first this makes grub-mkconfig use the bootfs property if set, because
the beadm tool changes that property to change the active boot environment.
Secondly for each kernel this adds bootable ZFS boot environment entries in
the advanced menu of grub.cfg by looking for valid boot environments and if
/boot resides in ZFS it checks if that boot environment has that kernel.

I did and grub-mkconfig failed long before reaching this, because
grub-probe failed. Apparently grub-probe depends on the zpool command.

Do you mean that grub-mkconfig has its own $PATH and that I should
temporarily change it to the user's $PATH? If so, can the 10_linux script
see the user's $PATH?
