Thank you for the feedback. Please note that git-ubuntu is a very old snap that predates our Process for reviewing classic confinement snaps. Since then we have various facilities for allowing applications to use git in various ways, specifically The personal-files interface which snaps like gitl and icdiff use effectively without classic confinement. It is for these reasons that we are asking questions to understand the best path forward.
The dvc run command makes it clear that this snap requires classic to function, since it can specify any user-provided command that might do anything, and these commands would only function correctly with the host’s filesystem, not the snap’s runtime if it were strict. Looking at the upstream website, dvc basically falls into the existing classic category of “tools for local, non-root user driven configuration of/switching to development workspaces/environments”. Ie, all the context for the ML experiment is saved in git by the user, then checked out (or pulled down on another machine) by the user, and then the dvc run command is invoked by the user.
The requirements are understood. @advocacy - can you perform the vetting?
