How does this compare with termux? What are the advantages? (termux is still available on fdroid https://f-droid.org/en/packages/com.termux/)

I am guessing it is avoiding all the android-lockdown problems besetting termux... though termux still works for me on android 11...

It uses proot - doesn't that come with a substantial performance hit?

It's a fork of Termux with all the same restrictions as far as I can tell. The difference is that it uses Nix OS instead of the Termux repos, which has more software available.

OK, so it's a normal unix release, and uses proot for a virtual directory structure. It says it only uses the terminal emulator from termux.

termux doesn't use proot - its distribution has all paths rewritten (usually in source) to cope with the android filesystem (and other changes). I'm always surprised that this hackery works so well!

Therefore, I'd expect identical programs to be slower in nix-on-droid.

Probably. But modern phones are well beyond the power needed to run linux programs at useful speeds. Termux first came out over a decade ago, IIRC. Back then phones were much less powerful.

Very true, though for compilation, perceptively-instant is nice rather than a few seconds.
