Hi,

on my new PC I'm forced to use UEFI, since the new Intel GPU doesn't
allow to select CSM, for this reason I migrated from syslinux to grub.
I used syslinux from my Arch Linux install and now I'm using grub from
the Arch Linux install. The pitfalls I experienced booting Alpine were
not related to the grub bootloader.

It's not that terrible as it does sound. Without all those grub configs
for the configs and automation, it's possible to write a clean syslinux
alike config for grub [1].

Regards,
Ralf
