Oh I didn’t realize. I wonder why they would do that? Either way it’s not a huge deal - the main problem with TrueNAS Scale is that you actively cannot install Docker onto it because it will conflict with the normal TrueNAS Scale app system. There are technically ways to get Docker working on a TrueNAS Scale system but they’re unsupported and likely to break frequently on updates. Debian and OpenMediaVault should behave similarly in terms of getting Docker set up.
