14 config CONFIG_FEATURE_USE_INITTAB
15 bool " Support reading an inittab file?"

28 config CONFIG_FEATURE_INIT_COREDUMPS
29 bool " Support dumping core for child processes (debugging only)?"
31 depends on CONFIG_INIT
33 If this option is enabled and the file /.init_enable_core
34 exists, then init will call setrlimit() to allow unlimited
35 core file sizes. If this option is disabled, processes
36 will not generate any core files.
38 config CONFIG_FEATURE_INIT_SWAPON
39 bool " Should init run swapon if short on memory?"
41 depends on CONFIG_INIT

44 will run '/sbin/swapon -a' to add swap memory.
46 config CONFIG_FEATURE_INIT_SCTTY
47 bool " Support running commands with a controlling-tty?"
49 depends on CONFIG_INIT
51 If this option is enabled a command starting with hyphen (-)
52 is run in its own session (setsid(2)) and possibly with a
53 controlling tty (TIOCSCTTY). This is not the traditional init
54 behavour, but is often what you want in an embedded system where
55 the console is only accessed during development or for maintenance.

58 bool " Should init be _extra_ quiet on boot?"
