Hey @Flox! Thanks for the reply.
Yea, I’ve seen those in my searches. The second one (from Haioken) in particular stood out as being very similar. I’ve tried a few methods of creating the install USB and even tried legacy rather than UEFI boot, but neither have worked. I can’t think of much else other than hardware detection/compatibility after exhausting that route.
I’ve seen the solution for installing elsewhere and moving the drive after the fact in a few places. I’d normally have just gone for it and tried it, but don’t have any other non-Ryzen hardware around with NVMe support at the moment. 
I saw someone elsewhere do an install to a regular SSD and then copy from there to the NVMe drive using clonezilla. That might be a viable option if I have to go down that route. T̶h̶a̶t̶ ̶w̶o̶n̶’̶t̶ ̶r̶e̶q̶u̶i̶r̶e̶ ̶m̶e̶ ̶t̶e̶a̶r̶i̶n̶g̶ ̶a̶p̶a̶r̶t̶ ̶m̶y̶ ̶w̶o̶r̶k̶s̶t̶a̶t̶i̶o̶n̶ ̶e̶i̶t̶h̶e̶r̶,̶ ̶s̶i̶n̶c̶e̶ ̶I̶ ̶s̶h̶o̶u̶l̶d̶ ̶b̶e̶ ̶a̶b̶l̶e̶ ̶t̶o̶ ̶d̶o̶ ̶i̶t̶ ̶e̶n̶t̶i̶r̶e̶l̶y̶ ̶o̶n̶ ̶t̶h̶e̶ ̶n̶e̶w̶ ̶b̶o̶x̶. (EDIT: Scratch that. Having the regular SSD available didn’t make a difference. It seems to be specifically the platform, and sadly, I don’t have any non-Ryzen hardware atm). If there are other easier/consistent solutions though, I’d definitely be open to them. Lol.
EDIT 2: I’ve been looking at the OpenSUSE rebase offerings as a possible option as well. I can see here and here that things are getting pretty far along, but not quite there. I assume being able to install an updated base of OpenSUSE would likely bypass my issues.
There are several places in those two threads that mention what current issues there are or what isn’t working yet. Is there anywhere that has a more complete & up to date list (there doesn’t seem to be a tag for it on the github tracker) of what needs to be done? I am a developer for my day-job (albeit without any substantial experience on OS-level stuff) so I can definitely try to document/assist (or even contribute if it’s something I’m comfortable with) as needed.
How is the status of the btrfs interactions in the SUSE version? If something goes wrong and I need to reinstall the OS, that’s not a huge deal. As long as it’s still possible to re-mount the drives and import the pool (even if I have to do it command-line myself and have rockstor eventually notice it), I’d be willing to use it for my home NAS in this case. Anything important has cloud backups, so the NAS is mostly for media that would just be a time-consuming pain to re-acquire.
Is this a terrible idea? I understand that no one working on the project would directly recommend this as a solution, so I figured I’d bring the option up. Lol.
