Slavek, I'm working on the systemd user session tracking bug (1902) and I'm trying to figure out where to start chasing down how TDE knows when to kill a running process. I've found a structure 'sigaction' - is this the central bit of data to track through tdebase to see how/where process tracking/killing occurs? Help wanted - great wages + benefits :) -- David C.
