Hi fellow Guixers,
What would be the easiest way to prevent any package from a specific
commit (or generation) to be garbage collected?
E.g. I build a package, which requires certain compilers as native
input, and then I garbage collect. Then I don't want those compilers to
be collected.
Or package sources. Or something I built but did not actually install.
I'd like everything that corresponds to a specific guix commit (or
several) to be considered 'live'.
I can think of various hackish ways to approach this problem, but I'm
not experienced enough to quickly whip something together.
For example, I suppose it would be possible to calculate all 30000
derivation hashes, look which one are in the store, and then install
everything found into a profile.
And I tried to write a procedure that takes a manifest as input, and
returns a manifest that recursively includes all native-inputs of the
input manifest, so I could explicitly install all of those.
Maybe one of you has something on the shelf already?
Thanks,
Hugo
