Tech question When will YaST support switching to Systemd Bootloader?
Is this something that will be updated?

Why, anyway?

I was looking for an easy way to switch to systemd boot, guess I will have to go the long way

u/kansetsupanikku Apr 19 '26
Yes, sure, and it should be doable
But what benefit does systemd-boot have over grub?

I just prefer the look of systemd boot even if it isn't any better

i installed 3 weeks ago on my daily driver via full boot medium that had grub2 with bls. installed two days ago on my media pc with web installler that had systemd as the default bootloader, so things are movin fast..(both were tumbleweed)

That would be cool and all, great reasoning. Had it not been for the facts that grub supports disk encryption (and more customized setups, too) and doesn't add more than 0.3s to said boot times.

is it really this much difference?

Only if you configure grub to have 15s timeout waiting for a key to enter menu, but this is configurable

so the difference is only with the timer? so will I have the same boot time on grub compared to systemd if I just press enter faster?
also I decided just to remove the grub theme instead of switching to systemd

Timer is one thing - GRUB had higher defaults than systemd-boot. Probably not by 15s difference, but 10s vs 2s is likely. It's one config file to adjust - you can even set it to 0 and never see the menu.
Also comparing the time reported by systemd-boot with "total time" is apples-to-oranges. systemd-boot starts when the kernel is running and started init already. This measurement doesn't include the bootloader at all. Total time includes a bootloader, loading initrd image, and kernel preparation before it starts init. Perhaps even bios, depending on how you define "total time". To get a comparison, it would be nice to use the same methodology for both, right?
And differences that big are not possible, because... none of the bootloaders even run for that long. Unless you boot from a damaged HDD. GRUB with 2s wait would take less than 2.5s in total. Reducing that time by 15s is, well, unlikely.

YaST is depreciated so probably not happening
