bug#48166: Dont stop the upgrade process - Better guix handling when Package failed to build

I don't think --keep-going works as you expect it to. When you do guix upgrade, guix creates a derivation for your new profile and proceeds to build it. If it has dependents that need to be built (packages that were updated), it builds them as they are needed to build the new profile.

If one of them fails, guix fails early by default. --keep-going will, well, keep going and guix will build the rest of the dependents that are independent from that failure.

However, it will eventually fail (late) when it tries to finally build the derivation for the new derivation: itqdepends on other derivations that already failed. Not sure how it reports the failures, but it might be easier to list all the failures in one try, and apply your workaround.

To do what you want (create a new generations ignoring failures) is not easy to implement. We would have to "change our mind" and build a different derivation for that new profile.
