Is there a way to downgrade boot2docker.iso for latest docker-machine?

Hi all,

I just started having a problem this morning with docker on Mac OS X. I recreated a dev vm and suddenly my builds no longer work (can’t tag from our existing build system). After digging all day, I suspect that my boot2docker.iso was updated and for whatever reason, our builds are not compatible with the latest docker (we are using 1.9.1).

Is there a way to not update boot2docker.iso so that I can force an older iso to test this?

Thanks!

I just found out about --virtualbox-boot2docker-url, hopefully I can save someone else some time :wink:
