Too much verbosity

[yajo]

Running nixos deploy without --show-trace shows a trace if deployment has some error. Always. Possibly coming from here:

nixops/nixops/evaluation.py

Line 101 in bd6b955

+ ["--show-trace"]

it's a bad thing to have a trace if deployment failed ?

It is, if --show-trace was not added by the user. Usually a shorter message is more helpful if it shows the important source of the error.
