Hi

I recently wasted some time over this, so either the documentation needs
to be improved, or some parity needs to happen with rc.d script
behaviour at boot and at the console.

Take this snippet from /etc/rc

export HOME=/
export PATH=/sbin:/bin:/usr/sbin:/usr/bin
umask 022

The default environment for root has a different HOME and PATH which led
me on a merry chase working out why it worked fine on the console but
not at boot - basically I was running a daemon under the impression that
 it would pickup paths for /usr/pkg/sbin and /usr/pkg/bin.

I think a comment should be added to /etc/rc.conf about this along with
the above being moved to /etc/defaults/rc.conf. Hopefully then, rc.d
scripts should be similar behavior between boot and console.

Something else for discussion should the default path be changed to
mirror the default path for root? This would allow a daemon included in
base to find an optionally installed program from pkgsrc by path. The
daemon in question is dhcpcd, the program in question is openresolv. I
don't really want to go about coding dhcpcd to try and search every
package path around either :)

Thanks

Roy
