Grub Customizer VS systemd-boot (Gummiboot)

Grub-customizer hasn't been updated in 3 years, I wouldn't let it near my config with a ten foot pole. Source: over 2 years ago

If you can install Ubuntu packages, https://launchpad.net/grub-customizer might do it. Its a GUI to edit grub entries, seems easier than switching bootloaders to me. Source: over 2 years ago

Grub-customizer is supposed to be maintained on Launchpad Https://launchpad.net/grub-customizer But the last version of the package was released 2018-10-13 and the main developer only responded to 1 bug report this year - but it is confirmed to work on Ubuntu 19.10! Source: over 2 years ago

That being said, if you follow the instructions on the Arch wiki, you can probably install/enable systemd-boot then delete grub when you're done. I've switched a system from grub to systemd-boot and I remember it being pretty easy using the bootctl command. Source: 5 months ago

In my case I'm using systemd-boot with unified kernel images that you can generate with dracut (there is a link in there). Source: 11 months ago

I don't think there's anyway around using a bootloader. There are more minimalistic options compared to grub (grub2), like systemd-boot https://wiki.archlinux.org/title/systemd-boot. Source: about 1 year ago

Arch wiki page on just systemd specifically. Source: about 1 year ago
