Currently the zipl setup as done by debian-installer uses a fixed config
file and relys on symlinks /boot/vmlinuz and /boot/initrd.img.  The
kernel team intends to remove support for those symlinks in the near
future.

We need to find another way to handle those, like creating BLS files,
also for grub.  I try to see how we can do that.

Hi Bastian,

Had a quick word with the zipl maintainer Peter Oberparleiter.
He was mentioning that there wouldn't be much problem in switching to a
BLS config (https://uapi-group.org/specifications/specs/boot_loader_specification/) as zipl
already supports that and this config approach is already in use on RHEL.

Please do mention if you see any additional zipl requirements in this area (or something that doesn't
work).

Thanks & Regards,
Pranav
