> The list in _Advanced Programming in the Unix Environment_ That list answeres just a tiny subset of my questions (mainly, that indeed SYSV is the system where a session leader automatically acquires a control tty if it happens to open a tty). Strangely, it doesn't mention the re-parenting at all.
Perhaps I should state more clearly what my questions are -- is the re-parenting to PPID 1 just to have someone wait()? -- what exactly is the point (save sanity) of redirecting stdXXX to /dev/null? -- which flags to open() /dev/null with for stdXXX? -- is opening /dev/null and dup2()ing to stdXXX just an optimization? -- what's the point of some daemons assuring the outer process doesn't exit before the innermost actually runs? And: -- is there a way to detach in a shell script?
