Description Yuri Victorovich freebsd_committer 2016-11-06 21:04:49 UTC
In https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207129 I implemented the instances functionality for security/tor, when additional instances of Tor can be run under the umbrella of the same service.

I am going to generalize that functionality so that some other servers can use the additional instances too.

This will be implemented in /etc/rc.subr.

> # /etc/rc.conf will include the lines like this:
> <name>_enable="YES"
> <name>_instances="inst1:<param1>:<param2>{:...} {inst2:<param1>:<param2>{:...} {...additional instances...}}"
> <name>_disable_default_instance="YES"

Then service commands
> # service <cmd> <name> {<instance>}
will execute the command <cmd> on all defined instances, or on one instance <instance>.

rc scripts will have to include the process_instances call with instance declaration:

> process_instances "$1" "$2" "<param1>/<param1_type>:<param2>/<param2_type>{:...}" || return $?
> ...
> run_rc_command_with_instances "$1"
