@geofft Do you know what permissions we need so that different processes, e.g. running in different docker containers, can use the same lockfile? |

There was a problem hiding this comment.
666 is clearly better than 777, I don't know POSIX well enough to know if we can go tighter than that

This removes executable permissions while retaining global read / global write.
It's been suggested we should use 0o644 instead, dropping the global write permissions (i.e., just the owner can write), but since we're taking an exclusive lock I don't think that would work and we'd regress the issue that was solved by updating the permissions. I think we'll need to revisit the locking scheme if that's the goal, but regardless, this seems like a net improvement.
