I have many jobs that use the same set of git repos and/or submodules.
I'm using the reference repo feature of the git plugin to conserve space, but this still requires some bootstrapping on each node where I want to use the repo.
What I'm imagining is a mode of operation where there's a top level mirror clone for each node and repo at the start of a job by default.
Let's say I have a git repo like:
That has submodules:
What I'd want is on the node when the job first runs, it does a mirror clone for each component to an encoded directory:
When the job runs it would check first for a matching spec under gitrepos, and use that as a reference both for submodules and the main repo as necessary, eliminating the need to manually clone and set a reference repo.
For some users this could be a big savings of time/space.
