>Description:
The file /etc/pkgpath.conf is undocumented and its rationale is unclear.
>How-To-Repeat:
man pkgpath.conf
jmacs /etc/pkgpath.conf
jmacs /etc/defaults/pkgpath.conf
>Fix:
I don't understand the purpose of the following trivial definitions:

  pkg_admin=/usr/sbin/pkg_admin
  pkg_info=/usr/sbin/pkg_info

If these are really needed, why not use which(1) or something alike?
