The benefit is that you have not only a clean git repo for the container,
but also not touching your working copy directory. But unless nobody else
raise any concern, I'm ok with your current proposal.

Makes sense. Also, having scripts on two directories can lead to confusion,
let's keep it in ci directory.

+1, maybe we should add it to the current ci scripts as well (+ use params
instead of setting it via set command, it should work in dash and busybox shell
as well).

Kind regards,
