<rekado>this little bug means that people are unable to actually switch R versions when rserver runs as a different user account.
<rekado>that’s because we write to their own “active session” and then attempt to read from root’s non-existent session
<rekado>it doesn’t outright throw an error; switching versions just has no effect
<PurpleSym>Ah, okay, I see. I thought we’d have to actually link rserver against pam.
<rekado>no, luckily we don’t have to. --auth-pam-helper-path could be set to *anything*, but for integration with existing PAM policies it should be something that links with the system’s PAM. The system-installed pamtester fits the bill.
