OpenSUSE: 4 months in

Maybe it is time for a little update, even if there is not much to say. After 4 months of running OpenSUSE Tumbleweed, I can honestly say I have not had a single moment where I’d thought I should maybe look for another distribution because XYZ is getting too annoying.

Of course it does have some annoyances. Some are with me, like running systemd-boot while it is not officially ready for primetime yet. Others are with OpenSUSE or my setup, like sometimes an update will bork the system and I have to do a snapper rollback. Fortunately, OpenSUSE makes this a 2 minute job and so far, rolling back the update and installing it again is all that is needed to fix the system and the update.

Other than that, I can’t even really think of anything. It just works. It runs, it runs fast, I have all the latest packages as you can expect using a rolling release and I just get to enjoy using my computer and play around with it. Both my desktop as well as my laptop.

It’s nice to be able to use the computers without this itch or little doubt that makes one go and look for greener pastures.

I’m still impressed, really impressed with OpenSUSE. More should be using it, it really is that good. And a bit of counterweight to the giants like Canonical and Redhat would be nice too.

Have a good one.

systemd-boot on OpenSUSE

I am weird sometimes, I know. Ever since I used Pop!OS, which uses systemd-boot as default boot manager, I have fallen in love with it. The simplicity and speed of systemd-boot versus the complexity and bulk of GRUB2 just won me over.

Mind you, GRUB2 is very good at what it does. It’s just that I don’t need all it does. All I need is to boot my machine, nothing more, nothing less. My laptop, on which I am typing this, only has OpenSUSE installed. No dual boot, nothing. My desktop boots OpenSUSE and FreeBSD at the moment, but they do so from seperate disks with their own bootloader. Nice and simple.

Neither need the features of GRUB2.

That said, changing the bootloader is tricky. It’d be nice if OpenSUSE would let you pick systemd-boot at install, so you don’t have to muck with it. However, since end of September, OpenSUSE officially supports systemd-boot.

So, I just had to have it, starting with my laptop.


Note: I do not use secureboot. Do not blindly follow this tutorial if you are using secure boot: it will break your system. You can do it, but it requires more steps then I will outline here.

First, check if /usr/lib/bootloader/systemd-boot exists. If it does, you’re good.

Remove all OpenSUSE entries from the EFI boot menu, and all others you do not need:

# efibootmgr --delete --label opensuse-secureboot

Do this for each entry you do not need or want. You can see what entries there are by just typinge efibootmgr without any options.

Next we want to update the configuration, so it knows we are going to use systemd-boot.

# vi /etc/sysconfig/bootloader 

Change from (probably) LOADER_TYPE="grub2-efi" to LOADER_TYPE="systemd-boot"

Install the systemd-boot utils to add support for snapshots. We are running OpenSUSE, we do want support for our automatic btrfs snapper snapshots.

# zypper in sdbootutil-snapper sdbootutil-rpm-scriptlets

If zypper complains that it needs to remove GRUB2 to do this, confirm by choosing the solution that will do so. It will both add all the files required for systemd-boot to function and remove all grub2 related files that you will not be using anymore.

Then we want to install our kernels, including snapshots so we can actually boot as we do not have a bootmanager installed right now!

# sdbootutil install
# sdbootutil add-all-kernels

Now we’re done. Systemd-boot is installed, GRUB2 is removed and we can reboot our system and enjoy a fast and less bloated setup. If you want to get to the boot menu to boot from a snapshot, just hold the spacebar while booting and it will pop up.

Issues / challenges

  • Initrd / ramdisk does not get updated after installation / update of kernel drivers, ie NVIDIA graphics drivers. This can be solved by manually generating a new initrd file and copying it to the appropiate location, replacing the old one but should really be done automatically. Bug is filed.
