After waiting some weeks for Arch to be re-released I finally booted an Arch image. Not a week had passed and some kernel upgrade had already made the system unavailable (no network on vm). I forced nothing, just ran sudo pacman -Syu as I always did on Linode.
Support didn't care. For days I tried responding to the ticket that I opened, talking to them on the irc, via mail. Nothing. I tried to request help to at least recover the files. Nope, nothing they can do.
I did not understand the true value of good support. Now I do. Back to Linode.
The fact that he didn't get any help is a problem that is what support is supposed to do and if he expects a higher level of support than Digital Ocean provides and Linode provides that I see no problem.
(The use case in this thread is backups as voidlogic mentioned.)
And yes linode has this: http://www.linode.com/wiki/index.php/Finnix_LiveCD_Recovery_...
This was DigitalOcean's fault, for not supporting changed kernels without providing safeguards against kernel updates.
