Hi.

Sorry for lack of proper troubleshooting and vague information, but
I don't have time to look into this properly.

Sometime ago, I think after this year Python upgrades rc.d(8) script
stopped working with salt minion (I don't have master on -current
OpenBSD). I see that on OpenBSD 7.9 proctitle works correctly, so it
was after the 7.9 release.
