Thanks for the info. I think the easiest solution is having the internal drive with the stable Ubuntu release for production, and having the development release in a pen drive. Then configuring the BIOS to boot from the pen drive first if connected, so for testing you only have to plug it in.
And if you want to keep the image upgraded, you only have to upgrade from the Terminal. Perhaps I shall document that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1687333 Title: Provide a method for installing Ubuntu directly into an USB drive To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1687333/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
