@algorandskiy , the Ci complains...

Label error. Requires exactly 1 of: New Feature, Enhancement, Bug-Fix, Not-Yet-Enabled, Skip-Release-Notes. Found: user-facing, external contribution

I'd make resolveDataDir a function taking dirs as its argument, and update cmd/algocfg/datadir.go as well, and probably move it to cmd/utils. But this also LGTM

I did not notice the code-duplication, there are even more resolveDataDir and other DataDir related duplicates.

Would prefer to handle them in a separate follow-up issue/PR (see #5068).

But this also LGTM

Ty! (btw: fascinating fast PR processing!)

@algorandskiy , somehow the github auto-close-issue did not trigger, still open: #589
