I think I understand how it works (in a somewhat higher level of being between the plain user and the interested admin ... not understanding all the exact details on the lowest level) .... but I always feel that it is hard to "do it right", even when I follow howtos and dig through docs. Maybe it is related to being interested in latest development, for sure I have to accept hitting bugs and issues when I run unstable software. But on the other hand: over the years the "best practise" changes ... for example what your fstab should/could look like or how to partition your harddrive. Do I have to change things because it's better that way, is it worth the effort ... ? Should I go away from RAID because LVM could stripe/mirror by itself? Should I go away from LVM because it's kinda old technology? ... all these things to consider. And then you get into issues with block sizes and stuff, where I always wonder why *I* have to type all these parameters ... why doesn't modern software just come with this knowledge inside? .... you know *sigh* ;-) >> I am not so far to skip the initramfs -> I don't *know* that, I >> just tested removing the line from grub2 and it failed finding the >> root-fs. > > I've never had an initramfs, seeing no need in my case to keep /usr > on its own partition.

My desktop once was set up to boot gentoo via UEFI (Grub2), worked OK, then something happened and I spent hours to fix it, then went back to BIOS/MBR. I just thought I could set that up now that I clean through my disks and partitioning. One of my thinkpads boots via UEFI, that was rather straight to set up and works fine. >> Maybe I learn more soon ;-) > > I sometimes say that life is just one long journey of discovery :-) Definitely!
