I have a zeroshell box with a big setup and now it fails every other week because of some issue with the DNS service. The restore process has been horrible. I have lost the subscription and everything is so big that I can not restore except to a backup that takes literally hours to come up again. And then I was thinking on keeping a profile as a reserve. But once the box fails miserably I can not select the backup profile. What can I do to select a profile at boot time?
