[Feature requests] nixos tests

[Mic92]

if there are no tests for a given package, I have to build the package myself anyway to test functionality.
A green nixos test is more actionable.

[grahamc]

Is this asking for a thing like @grahamcofborg test <testname>? or something else?

[Mic92]

When I call @grahamcofborg test ferm,
borg could do the following:

$ nix-build ./nixos/release.nix -A tests.ferm

A time limit would be recommend, because some broken tests tend to loop infinite.

[grahamc]

Don't the tests already have a maximum run time of 15min? or some timeout like that?

[Mic92]

I am not aware of a time limit.
