daemon control scripts
The /etc/rc.d directory contains shell scripts to start, stop, and reconfigure daemon programs (“services”).
Services installed from packages(7) may be started at boot time in the order specified by the pkg_scripts variable from rc.conf(8); the order will be reversed during shutdown. Services comprising OpenBSD base are started by rc(8).
The options are as follows:
- Setting this option will print the function names as they are called and prevent the rc.subr(8) framework from redirecting stdin and stderr to /dev/null. This is used to allow debugging of failed actions.
- Setting this option will force operations with the given action. If daemon_flags is set to “NO”, execution will continue with the script's own defaults unless other flags are specified.
Each such script responds to the following actions:
Daemon control scripts use a fixed number of sh(1) variables when starting a daemon. The following two can be overridden by site-specific values provided in rc.conf.local(8):
- Arguments to call the daemon with. If set to “NO”, it will prevent the daemon from starting even when listed in pkg_scripts.
- User to run the daemon as, using su(1).
To obtain the actual variable names, replace daemon with the name of the script. For example, postgres is managed through /etc/rc.d/postgresql. To run the daemon using a site-specific user account, define the following in rc.conf.local(8):
Each script may define its own defaults, as explained in rc.subr(8).
daemon_class is a special read-only
variable. It is set to “daemon” unless there is a login class
login.conf(5) with the same name as the
rc.d script itself, in which case it will be set to
that login class.

- Functions and variables used by
rc(8), rc.conf(8), rc.subr(8)
The /etc/rc.d directory first appeared in OpenBSD 4.9.
