Comment 2 for bug 275912

Yes, it would make things easier but it would also take a long time before you can do anything if you have to wait for it to search a complete system every time. You'd get in trouble if you have, for what ever reason, multiple versions of bzr on a system as well. This latter isn't unlikely if you have it on an USB stick. You might plug it into a system which already has bzr on it but you want it to use the version on the USB stick.
