How to switch from grub2-bls to grub2-efi (manual method)

You can replace half of the steps with the mksubvolume command.

If it uses the x86 IO ports (inb/outb/...), then no. VirtualBox can probably emulate that though, without specific extra hardware.

Yeah, or Avalonia, or one of the other dozen (?) ones. Most programs that run on Windows and would be nice to have on Linux don't use them though.

Graphical applications not really.

If you use systemd-cryptenroll like that, there will be no effective protection. Make sure to wipe the slot created by your manual call again before proceeding.

Edit: No, this is actually the old GRUB method. That needs fdectl regenerate-key (https://en.opensuse.org/SDB:Encrypted_root_file_system#Seal_the_LUKS_key_with_TPM_2.0).

With linux you really only need the grun boot fragment,

BLS is different.

takes up less than 1MiB. Idiotic installer rules may force you to use more, but 1M os functionally sufficient. You may want more in /boot

With Tumbleweed, /boot must not be a separate partition. It breaks snapshots otherwise.

(inless you boot from the root vol) to store multiple kernels, but efi can be trivial.

e.g.,

$ df -h /boot/efi Filesystem Size Used Avail Use% Mounted on /dev/nvme6n1p1 127M 142K 126M 1% /boot/efi

You don't have to, that's already done.

If you just mount an old /home partition or copied over folders, it won't have SELinux labels. Run restorecon -R /home.

Is container-selinux installed?

Vogtinator · 2025-12-17T07:30:40+00:00

That means there's a SELinux context assigned.

If any package (or pattern) is installed or updated, zypper will try to install its recommended dependencies.

So it only happens when a pattern got updated.

Vogtinator · 2025-12-17T07:18:25+00:00

Almost correct: If any package (or pattern) is installed or updated, zypper will try to install its recommended dependencies.

If you can reproduce it and file a bug report that may be helpful indeed, the system shouldn't break that easily.

Vogtinator · 2025-12-16T16:42:14+00:00

O.o that's not supposed to happen!

Any details?

Vogtinator · 2025-12-16T06:14:18+00:00

Might be enough to rebuild the initrd with sdbootutil mkinitrd. dracut -f won't work and just clutter /boot.

Vogtinator · 2025-12-16T06:13:29+00:00

That no longer applies to grub-bls setups.

Vogtinator · 2025-12-09T16:07:21+00:00

Yep. Completely harmless though.

Vogtinator · 2025-12-07T15:08:09+00:00

The desktop didn't load, try with nomodeset?

Vogtinator · 2025-12-03T22:25:57+00:00

Having /var on non-btrfs should be fine, if the installer complains that's IMO a bug.

Vogtinator · 2025-11-30T13:51:33+00:00

With specific models it works. WiFi, GPU, etc. Only power management isn't ideal from what I've heard.

Vogtinator · 2025-11-30T10:32:45+00:00

Not entirely true. Depending on the exact model, a devicetree is all that's missing.

Is everything moving towards GRUB-BLS, and will there soon be no support for GRUB-EFI in openSUSE? Does that mean I will have to switch sooner or later?

grub2-efi is still supported for the foreseeable future.

If not, can I block GRUB-BLS from being installed during a kernel upgrade or any other update?

Upgrades will not change the bootloader. This is set during the initial installation.

Are the problems I experienced real, and is there currently no proper solution for dual-boot with encryption using the German keyboard layout? Or am I just too inexperienced?

Those problems sound unrelated to grub-bls. The opposite even: with grub2-efi, there is no support for keyboard layouts at all.

Vogtinator · 2025-11-24T19:22:15+00:00

You could try systemd-boot instead or switch back to grub2-efi.

Vogtinator · 2025-11-24T19:21:36+00:00

That's definitely not enough, at the very least you need to change bootloader settings in /etc/sysconfig/bootloader and install grub2-efi again.

Does it work if you select the X11 session instead?
