Depenguinator "Upgrades" Linux to BSD

Thanks to a new depenguinator, it is now possible to upgrade Linux systems to run FreeBSD 5.x without requiring anything more than an SSH connection." Clever idea.
Use debootstrap. It will create a minimal install in any folder. Then chroot, and there you go, a small Debian system. Using that, you can either install Debian on another partition while running another distribution, or I suppose you also could replace your current install with Debian by booting into single user mode, and replacing your old system with Debian.
While you should be able to simply chroot into your new system and start adding stuff, I'd be a very good idea to boot it first. Debian will need to run some scripts on boot to finish configuring itself.
I'd go with the first option. The second one is too easy to screw up if you don't know what you're doing.
"having to do a make world on 300 boxen"
/usr/obj (and /usr/src as well?) as nfs, mount it on your 300 boxen, and you only need to install the shiny new bsd with 'make installworld'. That's it. So it is actually quite easy to deploy on a large server farm. You would go the same way with the ports btw: build on one machine and have it make pakcages, than install the packages with pkg_add -r whatever on the rest of the machines. Neat. :)
Not any more, and 'make world' is being deprecated in favor of 'make buildworld'. The difference is, that 'make buildworld' is totally self contained. You do 'make buldworld' on one machine, export
