When my Ubuntu server starts up, I see a message that says:
kernel: [11.895392] init: failsafe main process (631) killed by TERM signal. I would like to know what process this is but I'm not sure where to look. When I search through my
kernel.log, I don't see any evidence of processes starting and being given an identifier (PID).
I'd like to investigate my boot message (failsafe main process killed...) but first, I need to answer the question: When a process starts, where is that logged and does the PID that is assigned to it get logged as well?
I understand that a process will write a PID file to reference later as necessary, but once the process is killed, can I find out what PID it used to have?
