Re: Bug#791857: ITP: daemonize -- tool to run a command as a daemon
Of course, we shouldn't expect everyone to use systemd-run because that's locking into an init system which should quite obviously be avoided. That, again. The person who suggested using systemd merely pointed out that the task of turning a regular process into daemon is trivially solvable using systemd-run. This kind of implies that if the OP uses systemd, they could just read the appropriate manual page and have their task solved. When I read it, it came across a bit different from that. It sounded like that was to be considered the approach instead of one option. Related to a bit further down...

Two points: * It seems you have missed a message in this thread mentioning the `daemon` package which is in Debian (since ages) and is able to daemonize a regular program. You're right. I missed (spaced on) that note. Which helped contribute to my feelings above. I guess my argument is invalid. I'm sorry for the noise then! * Not to bash the maintainers of `start-stop-daemon` but this program is sort of a hack as it can't do most of what's expected from a daemonizer: it can't capture the standard output streams of the child it spawns and redirect them to syslog, and it can't restart the child when that dies. It can be a pain in the bum, but does (mostly) work... I need to start playing with daemon! -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Bug#791857: ITP: daemonize -- tool to run a command as a daemon

Richard Stevens’ 1990 book, UNIX Network Programming (Addison-Wesley, 1990), a daemon is “a process that executes ‘in the background’ i.e., without an associated terminal or login shell) either waiting for some event to occur, or waiting to perform some specified task on a periodic basis.” Upon startup, a typical daemon program will: . * Close all open file descriptors (especially standard input, standard output and standard error) * Change its working directory to the root filesystem, to ensure that it doesn’t tie up another filesystem and prevent it from being unmounted * Reset its umask value * Run in the background (i.e., fork) * Disassociate from its process group (usually a shell), to insulate itself from signals (such as HUP) sent to the process group * Ignore all terminal I/O signals * Disassociate from the control terminal (and take steps not to reacquire one) * Handle any SIGCLD signals . Most programs that are designed to be run as daemons do that work for themselves. However, you’ll occasionally run across one that does not.
