>Description:
Having postfix enabled (the default) adds 20 seconds to the boot time of a 
raspberry pi. Not sure what the script is doing, most other scripts complete in 
less than a second.
>How-To-Repeat:
Add a timestamp to the rc_log_message call here:

  http://nxr.netbsd.org/xref/src/etc/rc#309

e.g.:

  rc_log_message "[$(date) running $1]"

and inspect /var/run/rc.log after startup
>Fix:
Not sure. postfix=NO gives the 20s back though.
