Why is /bin linked to /usr/bin?

[jwwskymaster]

This is causing a problem placing a front end in /bin, that runs before executing the real one in /usr/bin.

Sample script in /bin called mycommand

#!/bin/sh
# Do my stuff
.
.
.
exec /usr/bin/mycommand

A sample use of this could be to log every use of a system command, that normally lives in /usr/bin.

If PATH is set like PATH=/bin:/usr/bin

Then all is fine on systems that do not link /bin to /usr/bin.

What is the purpose of linking them?
Is this something that is going to be changed?

I guess I can come up with a work around by adding a new directory like /frontend, and add that to the PATH like
PATH=/frontend:/bin:/usr/bin

This is the way of the future and is part of something called the usrmove project. It's not going away so you have to find a new way to do what you want.
