[Bug 2107381] Re: zfs + encryption fails with plucky iso dated 20250415 - Requested offset is beyond real size of device /dev/zvol/rpool/keystore

[Olivier Gayot]

I tested on noble using the desktop installer with the latest ubuntu-
desktop-bootstrap snap (rev 413) and latest daily ISO (20250801). The
installation went successfully.

When installing on a VM, I did run into an issue on first boot and filed
bug 2119293 (which I don't consider critical for .3 since it is not a
regression).

Marking fix released since the regression with the zfs luks header size
is addressed.
