[displague]

It looks like mergify is stuck on this validation phase. Is there any way to kick it?

[tstromberg]

@displague - a force push should help.

[tstromberg]

Also, I don't think this fixes #306 - which seemed to be around adding some kind of retry? Am I confused?

[displague]

@tstromberg Looks like this closes the issue described in #305 PR body, but not #306 which #305 was overextended to solve.

Hey @displague, do you know where/when setup.sh is used or when it's useful?

[displague]

@jacobweinstock Good question.

This PR was resurrected from another PR from a stale issue resurfaced through triage-party. It seems I may have applied a fix for a file we no longer use.

It looks like setup.sh is no longer part of the directions (at least not in a GH search of this project).
setup.sh (a diverged copy) in the boostrap project is used in the Terraform provisioner.
