Yeah, I got it. I've just wanted to get a more deeper explanation of your existing partitioning situation - I've set up RHEL derivatives on some very vague partitioning variations. Never thought that there could be the problems. Maybe it's just a GUI limitation?

I think it is almost certainly a GUI limitation. E.g. I have a ext4 partition that I usually mount on /other and preserve it when distro-hopping. I can't remember exactly but one of these things happened - it didn't detect this partition / didn't give me the option to preserve it / didn't allow me to specify the mount point for it. Had a similar issue with another partition too. I think I also had some minimum space related restriction that refused to go away. Wish I had taken notes/pictures.
