sure pexp matches the process (i.e. doesn't include the quotes).
It's a bit hackish but it allows things like these in rc.conf.local:
relayd_flags=-D IPS="1.2.3.4 2.3.4.5"
And we properly end up with...
$ grep ^pexp /var/run/rc.d/relayd
pexp=/usr/sbin/relayd -D IPS=1.2.3.4 1.2.3.5
... which matches what is in the process list:
root     14217  <snip>    0:00.01 /usr/sbin/relayd -D IPS=1.2.3.4 1.2.3.5
There's always the possibility that we have introduced a regressions with hand
crafted functions in rc.d scripts (mostly from packags), so watch out.
