And to update grub it seems the best command is “update-bootloader”
grub2-mkconfig
seems to work fine as well. I just installed openSUSE Tumbleweed on a machine yesterday and used that to add some kernel arguments. I was not aware of update-bootloader
at all.
Like what’s up with YaST?
Yeah, it's like an all-in-one launchpad for managing the system. I haven't used it much because I prefer using the terminal for most things, but it seems to work fine when I used it a bit (installing some repos and Nvidia drivers).
I installed SUSE after over 20 years and so far it's been quite a good experience. Very similar to the Fedora experience I would say, in the sense that you need to jump through some hoops to get Nvidia / non-free codecs and then after that it's smooth sailing. Let's see how it holds up in the longer term for me.
