Hello, I would like to add some usefull tip to
http://www.openbsd.org/faq/faq9.html
It is how to convert existing linux machine to openbsd on hosting providers
that do not provide openbsd support but do provide rescue mode.

It is simple like starting obsd install in qemu (in rescue cd mode), accessing
it via vnc, installing, fixing /etc/fstab /etc/hostname.if and rebooting whole
server to openbsd system.

Is it interesting addon?

Thank you!

Cheers,
Motvey
