What, efivars being mounted read-only? Quite sure. If I don't remount them read-write, "bootctl install" refuses to run at all. > Now it's fixed (by using something else) and I can't expect you to care, > but I am left perplexed. I wonder. Just possibly this is a motherboard or UEFI BIOS problem (or one I've caused it). When I first received the machine I couldn't get grub to install and run, no matter what I tried. That was 18 months ago, since when it's been running apparently happily using bootctl. -- Regards, Peter.
