Public bug reported:
Binary package hint: screen
If you manage to start a screen session before the rcS.d initscripts run
(e.g., because you do this at the "type password for emergency
maintenance" prompt, e.g. because you set SULOGIN=yes in
/etc/default/rcS), then /etc/rcS.d/S70screen-cleanup will delete the
socket for that screen in /var/run/screen. However, the screen process
will still be running... and as far as I can determine, it's impossible
to re-attach to that screen.
screen -wipe has the appropriate logic to delete only screen sockets
without corresponding running screen processes. Could we adapt the
initscript to check running screen processes via /proc/.../fd, or loop
over each user with screen -wipe, or something?
This is with screen 4.0.3-11 on Intrepid.
