Comment 2 for bug 1991661

I think one problem with changing this in systemd is that generators are allowed to be placed in /run [1]. While mounting /run noexec would not affect interpreted generators like bash scripts, it would prevent binary executable generators from being placed in /run.

If we find it necessary, we could carry a delta for this in Ubuntu, but I am not sure this is a change upstream will accept.
