No, Sir! No need to edit anything:

To run apache www server from startup, add apache24_enable=3D"yes"
in your /etc/rc.conf. Extra options can be found in startup script.
Your hostname must be resolvable using at least 1 mechanism in
/etc/nsswitch.conf typically DNS or /etc/hosts or apache might
have issues starting depending on the modules you are using.
root@testjail: # sysrc apache24_enable=3Dyes
apache24_enable: -> yes
root@testjail: # service apache24 start
Performing sanity check on apache24 configuration:
AH00557: httpd: apr_sockaddr_info_get() failed for testjail
AH00558: httpd: Could not reliably determine the server's fully
qualified domain name, using 127.0.0.1. Set the 'ServerName' directive
globally to suppress this message
Syntax OK
Starting apache24.

That's 3 commands to enter. Admittedly 2 more than on some OS that
blindly starts any service you install, but 2 steps more logical and
even a newbie can do this.
What could be done is that pkg looks for rc scripts in a package,
extracts the enable line and prints a message how to enable the script /
daemon permanently.
Like:=20
- To start the script "apache24" once run "service apache24 onestart".
- To start the script "apache24" at boot time run "sysrc apache24_enable=3D=
yes"
- The script "apache24" has the following optional settings for /etc/rc.con=
f:
apache24_profiles (str): Set to "" by default.
Define your profiles here.
apache24limits_enable (bool):Set to "NO" by default.
Set it to yes to run `limits $limits_args`
just before apache starts.
apache24_flags (str): Set to "" by default.
Extra flags passed to start command.
apache24limits_args (str): Default to "-e -C daemon"
Arguments of pre-start limits run.
apache24_http_accept_enable (bool): Set to "NO" by default.
Set to yes to check for accf_http kernel
module on start up and load if not loaded.
apache24_fib (str): Set an altered default network view for apa=
