I'll note any other issues after I've built, installed & tested & maybe hit (tweet) you on ultra (the fediverse/masstadon) with other notes.

Thanks for testing this. I should get around to updating this but sadly I don't have any Windows machines for testing that are conveniently available.

I did have grand plans of building this into a Debian package so it actually builds a proper installable package to use, but never quite got around to that.

I'll fork and clone it if there are any more things I find. Its a super useful script (last two times I read the script but did it all manually), if its only bugfixes I can help with that.

(I had grand plans for a script to convert ubuntu zsys bpool/rpool system to zfsbootmenu zroot only system... not happening... but I did just manually converted two distros with default btrfs root with grub-btrfs/snapper/timeshift to zfsbootmenu/sanoid... that would be a useful thing.)

Apparently successful, will test in next days

I think this should no longer be an issue, as my latest updates rework the script to use the kernel code from Microsoft's WSL kernel Git repo rather than direct from kernel.org
