Changing service in this way is undesirable, because it is designed to
emulate the environment on startup, which is in /etc/rc .

I'm not sure if modifying /etc/rc is a good idea either, because base
shouldn't care what PREFIX is set to, and hardcoding /usr/local is
inconsistent if PREFIX is changed.

All I can suggest is that something like;

PATH="$PATH:%%PREFIX%%/bin:%%PREFIX%%/sbin"

be put into affected rc files.  We could even create a macro for this....
