Opening a new terminal and typing the command firefox& inside, ps -l gives :



4 R 1000 23132 23104 99 80 0 - 2177945 - pts/27 00:00:07 firefox


If the terminal is closed, the firefox child process stays open !



Was it always the case ? Isn't firefox supposed to be closed as well ? Is there something new in a recent kernel or something ?



The result of ps -el|grep firefox is then :



4 S 1000 23132 1 14 80 0 - 2233312 poll_s ? 00:00:21 firefox


The PPID has been changed to 1.



What is responsible for this PPID change to 1 ?
