I use it and it works quite fine! Just a few differences you need to learn, all of which are noted on their concise wiki. It's best to think of Arch as the fallback distro, therefore all other information is obtained from the Arch wiki as normal.

I spun it up in a VM once or twice, but nothing serious yet. From what I have seen it's mostly about the different init systems. Anything else should be identical to Arch and you can use the Archwiki for that.
