As far as I can tell, /boot and /boot/grub are the same filesystem. After all, I didn't really do anything custom. Just your default LUKS installation with the boot efi stuff on sda1/sdb1/whatever, LUKS on 2 and LUKS encrypted swap on 3.
I did make a video. Nothing that's not showing up always. For a fraction of a second it shows something about slot 0 open, that's it. > On Dec 29, 2023, at 20:37, Richard Rosner <rich...@rosner-online.de> wrote: > > As far as I can tell, /boot and /boot/grub are the same filesystem.
