'nix-env --help' does not list it and 'man nix-env' has no explanation
for it.

Though, I must admit it sounds pretty self-explanatory - thx for the pointer!

Also I now found it in the nix manual under A.1 Common options:

--keep-going, -k

    Keep going in case of failed builds, to the greatest extent
    possible. That is, if building an input of some derivation fails,
    Nix will still build the other inputs, but not the derivation
    itself. Without this option, Nix stops if any build fails (except
    for builds of substitutes), possibly killing builds in progress (in
    case of parallel or distributed builds).

Is there a nix option for nix.extraOptions to make this the default for
all relevant commands?
