Well luckily I document when I make changes to any of the system config files, and there’s only been 3 I had to do, 2 for pulse/alsa, one for sssd because I couldn’t add users to groups, see here. So I think I should be fine on that front?
Well anyway yesterday before heading to bed I thought… why not just do a hybrid approach - upgrade first, if something goes wrong or is messed up after the upgrade I can still reinstall right…
Well, I’m hung up on the first step:
[tarulia@localhost]~% sudo dnf system-upgrade download --releasever=34 | tee -a upgrade_34.log
Before you continue ensure that your system is fully upgraded by running "dnf --refresh upgrade". Do you want to continue [y/N]: y

Error:
Problem: rdma-core-35.0-1.fc33.i686 has inferior architecture
- rdma-core-35.0-1.fc33.x86_64 does not belong to a distupgrade repository
- problem with installed package rdma-core-35.0-1.fc33.i686
(try to add '--skip-broken' to skip uninstallable packages)
Not sure why it’s not finding the groups, but that’s not something that I’m concerned about.
I’m not sure what it’s telling me with rdma-core considering that rdma is part of the kernel (I believe?), this worries me a bit 
Thing is, currently installed are both architectures:

So it’s not like it’s a downgrade?
Or is it telling me there’s no package for the x64 version in F34? Could hardly believe that… and how would I even check that (with system tools that is)?
