Yeah also this one is good, except user need to know "operating system 
declaration" beforehand but no issue anything better than the previous 
error message.

Just showing error messages of other distros.

But anyway your hints are better than the default used one, At least 
user can ask what i should use instead of "guix remove packages", but 
not oh what is profile guix talking about what profile i should use...etc

I hope you got the idea im trying to make.

(fixing the error message is not the ideal solution, ideal solution is 
to have friendly control on these packages. but this is for sure help as 
well)
