[pve-devel] [PATCH kernel-helper] add dedicated removable installation

[Stoiko Ivanov <s.ivanov@proxmox.com>]

seems adding `--removable` makes grub install ignore most other
information - e.g. the bootloader-id (guessed based on [0]).
add dedicated call with out `--removable` in addition

Seems that's the reason why our installer also 'rolls its own
removable' [1]

minimally tested with an ISO with this installed and an install with
ZFS on / (RAID1).
