I rented a dedicated server and want to run Sabayon Linux on it. Of course, I have no physical access, so I can't boot from USB stick or DVD, but my hoster offers me a rescue linux which is booted via network on demand and offers a complete shell based on Debian Lenny. To install Gentoo is no problem, because I can partition the disks from the rescue tool and then follow the Gentoo installation guide (extract stage3 etc.) and reboot as soon as I've setup a working system, but I did not found a tarball or something comparable containing a sabayon base system. Can I somehow "upgrade" my Gentoo to be a Sabayon after installation, or is there any other way to install Sabayon from another running linux?
