[MM3-users] Re: Adding members to a mailman3 mailing list

In my case, the mailman command I run invokes a bash file that looks like

IIRC shell scripts have a race condition, although I don't recall the conditions under which it's exploitable. Perhaps SELinux is sensitive to that. I don't really see how we can take responsibility for such issues except to document it as one user's experience.
