Hi!
Skimmed the forum but not found the answer I was looking for. Threads were already closed or I would have commented them.
I’m running Tumbleweed on Lenovo t480s with single boot and read that systemd-boot is now the default.
What’s the best way to move to it? I would not reinstall.
Thank you!
I have done a fresh install today and wasn’t given a choice of boot loaders, it defaulted to grub.
I see, don’t know why it was not default for you. Here is the source https://lists.opensuse.org/archives/list/factory@lists.opensuse.org/thread/4ZPQU7PV3ODS7WELADHE7F3SVBQDFIOP/
@steakhutzeee Hi see https://en.opensuse.org/Systemd-boot
These are my notes on switching to systemd-boot on a Leap 16.0 test install last October… NOTE /boot/efi partition size is 4GB.

This is super important, if your /boot/efi is less than this, then switching away from grub-efi is going to cause you quite a bit of grief when /boot/efi fills up.
I don’t know if the installation size of /boot/efi has yet been revised, so check before accepting the default partition scheme.
I have bls, can i move to systemd or do i need to reinstall?
I think you can simply change bootloader with the opensuse tools (as root):
zypper in systemd-boot
update-bootloader --loader systemd-boot
update-bootloader --install
update-bootloader --config
I think you also need to double check you have the sdbootutil utilities installed before installing systemd-boot
This 4GB requirement — which I think is primarily for systems with Nvidia cards — is a nonstarter for any long running installations of Tumbleweed and maybe also Leap.
Considering that some of these machines may even have LUKS on top it would make it so much more difficult to entertain the idea of repartitioning without a full wipe and reinstall
The question on my mind though is: How urgent is this systemd-boot migration? Is there something bigger coming in the near future that will take so much more space on /boot/efi even in the absence of an Nvidia card ?
To my understanding the culprit is that with systemd-boot, contrary to grub, kernels are residing in /boot/efi.
So depending on how much alternative kernels and snapshots are kept that might eat up quite a bit of space.
@newsense not related to any particular GPU, that size has been used by me for a number of years based on running Aeon which uses systemd-boot, I use it for all my installs these days whether grub2-efi, grub2-bls or systemd-boot, with or without btrfs and snapshots.
Who knows when the likes of grub2-efi will reach EOL, it’s all about preparing for a change… I still use grub2-efi here on my Primary Desktop, but at some point in the near future I see a fresh install coming…
I don’t see any urgent need for switching.
My desktop machine on Tumbleweed has a 500Mb ESP partition and systemd-boot.
During zypper operations I get messages about limited space left but so far, the post-install scripts have done their job and cleaned up the old kernel and initrd files.
So I am still surviving without manual rescue sessions…
Have you checked the usage of the ‘/var’ partition while performing the Zypper dup (dist-upgrade)?
On this Tumbleweed system, I have a 16 GiB ‘/var’ partition and noticed that, “btop” was indicating a 70 % plus usage during large upgrades …
/var is not a separate partition in my setup, it’s just a btrfs subvolume.
The notifications I am getting are definitely about /boot/efi partition.
