I don't know if that is a valid blanket statement. I think Darryl has some
channel changing scripts that reference the device names he created in his
udev scripts, so those would definitely need to be copied over to the new
system. However, whatever you copy from /usr/local/bin should be done
selectively, making sure you know what each file is and why you're copying
it. Also, you should probably only copy scripts from /usr/local/bin--any
compiled binary is best to be recompiled on the new system.
