Hi all, Given Guix builds packages in a container, is there any way of getting a file out of the build container for further processing?
In my use case - I generate some junit test XML output during the build process and want to render that to a webpage rather than send it to stdout as part of the build process? It is possible to export the nar file using guix archive --export, and possible to keep failed build artifacts using -K, but there doesn't seem to be a way to dump out a file from a successful build? Is this against the philosphy of purely-functional builds? Obviously it is a side-effect to dump out an XML file, but no more so than sending build logs to stdout? Is it possible to dump outputs without breaking referential transparency on the inputs - i.e. it should be possible to configure a directory that is write-only for the container, but can be read by users outside the container? Or am I missing something obvious? Thanks, Phil.
