Thanks for the suggestion.

We've reserved the last ubd device in your Linode config for this purpose (/dev/ubdh) -- it will contain a read-only filesystem that's universally mountable (ro) by any Linode and will contain the entire package contents of the distro's we provide.

I still have to figure out some disk usage reqs, and there is some testing I need to perform to make sure this will work correctly, but I thought you'd be happy to know something like this has been planned from the start.

Thanks again,
