[pve-devel] [PATCH pve-kernel-meta v2 7/8] proxmox-boot: allow to manually specify bootloader

Thu Mar 3 20:07:56 CET 2022


this commit adds the optional [--legacy|--uefi] arguments to `p-b-t
init` and `p-b-t reinit`. If provided the respective boot-loader is
installed (regardless of what is found on the esp, and of the
boot-mode)

This should make switching the boot-mode possible without the need
to boot into a live CD, chrooting and manually running the necessary
p-b-t commands.

added  [--legacy|--uefi] to the reinit subcommand as well.
