Hi current@ I want to add su to /rescue, but got stuck on pam. Old unix su didn't suffer from pam. There's no #define in su to turn off pam. Man src.conf says WITHOUT_PAM is deprecated & does nothing.
Can someone please offer a solution ? Or better to include a simple BSD su pre pam ? I would happily develop a patch for that.
