I’m using a dual boot of EndeavourOS with KDE Plasma and Gnome. I have edited the systemd-boot entries to look like this:
EndeavourOS (KDE Plasma)
EndeavourOS (Gnome)
But every time there is an update I have to redo the customization.
How can I make it permanent?
You would need to modify /usr/lib/kernel/install.d/90-loaderentry-fallback.install and /etc/kernel/install.d/90-loaderentry.install
What do I modify?
In /efi/loader/entries/*.conf
I edited title version sort-key
The scripts generate those values. You would have to find the places they were generated and figure out how to change them to do what you want.
maybe you need to do a pacman-hook in order to modify the /efi/loader/entries/*.conf after each update.
[Trigger]
Type = Package
Operation = Install
Operation = Upgrade
Target = *
[Action]
Description = mike-update.hook nach update systemd-boot zz
When = PostTransaction
Exec = /home/mike/bin/zz
zz which modifies the title in the/efi/loader/entries/*.confAre there instructions somewhere on how to do this?
No, you would have to read the scripts and figure out what to change.
Can you share your script?
I need to check over it first. My script is not generally exemplary, it just works for me with my limited programming knowledge. Maybe it can help to find out, what you need.
I will post it tomorrow.
It looks like I just need the version and sort-key to be permanent. The title doesn’t seem to change.
version KDE Plasma
sort-key 01
version Gnome
sort-key 02
Thanks
The title is what appears in the boot menu. My script modifies the title. So I can distinguish different intallations and releases in the boot menue. Tis is most important for me.
Here it comes:

I don’t know how to modify that script. So I guess I will just give up for now, but thanks.
