Hi, the last few comments in this bug have suggested there may not be a good solution for this problem.
As mdeslaur has pointed out in irc, one solution would be to have interactive su use a new pty for the session. Not trivial, but if the idea itself isn't objectionable I wouldn't mind trying a patch when I find time. Alternatively, we could simply update the su man page to recommend su only be used for increasing privilege (becoming root), and recommend other means for dropping privilege or switching users. -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
