no no no, NEVER use root as a user account :)
you have to setuid the freqset utility e installs in the module subdirectory
# chmod u+s freqset
This way whenever it is executed, it is executed as its owner, root, not as its
real user, you.
but some see it as a security hazard
To avoid sec problems, I set it to r-s--x--x rights and it is owned by root.

Linux is organic. Its not cleanly laid out. Its not specified in some
document. Linux is result of evolution as "nature" as dictated. This
drives some people nuts, but at the end of the day, it _works_.
