You missed the point. This would mean you would not be able to access
stuff like /home, which would make it awful hard to access user home
directories, unless you create symlink copies in the /compat/linux tree.

As long as you create the top-level dir in /compat/linux first, mkdir -p
will Do The Right Thing after that.

The port seems to install fine on my systems; it doesn't spam any existing
files or directories, so I'm not sure why you think linux_base-7 has a
problem.
