From 12677acf0a0bda4a863279ece65eccda6c36d6b1 Mon Sep 17 00:00:00 2001 From: "Anthony G. Basile" Date: Mon, 10 Dec 2012 14:49:39 -0500 Subject: CONFIG_PID_FILE_PATH: new configuration option for pidfile paths We set a default path for the directory where pidfiles are create when FEATURE_PIDFILE is selected. The default has no effect on applets which must specify a pidfile path on the command line to run, and it can be overridden by applets which optionally allow the user to specify the pidfile path. We also add pidfile write/remove support for klogd, ntpd and watchdog. For syslogd, we add a missing remove_pidfile() for better cleanup on daemon exit. Signed-off-by: Anthony G.
