Seems like the linux installer is not shutting down existing running instances properly (of pulse anyway). Previously this used to work. It would shut down existing 7 commands, install, then restart the service.
This is right after an install, you can see the launcher restarted, but not pulse:

After a while pulse simply crashed due to the .dlls/.sos changing. We have a cronjob that restarts pulse every couple minutes, so maybe this is always how it worked, we just never noticed?
