This isn’t specifically Bazzite related, but more of a Linux Btrfs thing.
So given that I am trying different desktop environments and such and you are not supposed to rebase, etc., and also I just still like to try different Linux distros along my Ublue daily driver, I have been installing a lot of OSes 
I got a bit tired of needing to back up my data, so I decided to do the “cool techy thing” to partition my drive into a system drive and data drive.
So after some issue I was having (on a mutable distro actually) I did some digging and found out that Btrfs subvolumes are basically a “software partition” and I would have been able to reinstall just the /root partition all along without physically splitting the data.
I feel very old school now. Or well I suppose now I am one of the “cool kids”? 
I just feel I keep overcomplicating things and 5 minutes later a different solution comes up, which I had not seen on Windows so I was totally unaware.
I feel like when I used to learn computers back when I was a kid, if was fun and very new.
