I decided to just run blendOS in a virtual machine; I had a bunch of data I hadn't backed up yet and was actively working on, and didn't feeling like switching yet given I had no experience with blendOS v4 - I've actually tried blendOS v3 before, back when v4 was in alpha, but it had practically zero documentation, not even `man` pages, so I gave up on it very quickly.
