|If you want to test changes for a specific service then stop and then
start
|that service. For example:
|
|# /etc/rc.d/cron stop
|# /etc/rc.d/cron start
|
|Wait a second or two between the stopping and the starting just to be
safe.

 =============



After I make changes to rc.conf, I always run

	sh -n rc.conf

to check for syntax errors, e.g., a missing quote, which can have a less
than positive effect upon the boot process.
