[Bug 2051999] Re: Grub2 2.06 has upstream bug that results in Non-booting with ZFS after snapshot of bpool.

[Mate Kukri]

Hi Mike,

Backporting and SRU-ing GRUB 2.12 to Jammy is part of the roadmap for
the Ubuntu 24.10 cycle. I would like to not make a more specific public
commitment right now, but it's inside the realm of possibility that it
will happen a lot sooner than October 2024.
