two questions on guix upgrade

[Andy Tai]

Hi, two questions on guix upgrade via

guix pull && guix package -u

1. Is there a way to tolerate errors in single package upgrade and keep the
others going?   right now I have opencv installed and opencv build now is
broken, so if I do the above command as is the whole 'package -u' command
would fail unless I explicitly exclude opencv from the update step.

2. is there a way to exclude packages that require local build?  I use a VM
with just 4 Gb of RAM running the guix distribution and the above command
may fail when upgrading and certain packages with no substitutes yet
available would be build locally and because of the low amount of RAM the
build steps would fail, again making the whole command fail.   It would be
ideal to have an option to just skip packages that would be built locally.

Sorry if I missed any existing ways to do these if already available..
