After a couple years on Fedora I decided to do one more Distro hop- to one I have little experience with, openSUSE.

But it seems the everything from the installer, philosophy, package manager, configs, and general way of working is just very different than every Distro I've tried before (Debian/*Buntu, Fedora, Arch, Gentoo)

Like what's up with YaST? It's like a system-wide settings/configs program plus a package manager front end unique to openSUSE?

And to update grub it seems the best command is "update-bootloader" - for example. This isn't standard on anything else afaik. Is there anywhere other than practice I can learn all of these quirks?
