2013-08-16init: don't srop unterminated processes' entries during inittab reloadPaulius Zaleckas
This feature was removed in 72c99af It is useful when process is removed from inittab and later added back, but never terminated. It prevents init from spawning duplicate. function old new delta check_delayed_sigs 176 182 +6 Signed-off-by: Paulius Zaleckas <paulius.zaleckas@gmail.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2013-08-16init: don't use fixed size buffer for commandDenys Vlasenko
We store init actions forever. 256 bytes per action means that a typical inittab of ~10 commands uses 2.5k just to remember command strings - which are usually _much_ shorter than 256 bytes. At a cost of a bit more code, it's possible to allocate only actually needed amount. function old new delta init_exec 224 248 +24 new_init_action 140 142 +2 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
