Since Yaifo hadn't been updated since version 0.2 for OpenBSD 3.8, I emailed Waldemar (the original author) and asked if I could take over the project. He said yes, so I am now the official Yaifo maintainer.
I would like to come up with a different name that more expresses that Yaifo is not a different installer, but an enhanced version of bsd.rd (with sshd). I'd also like to come up with a logo. After I get a new name and logo, I'm going to set up a SourceForge project.
If you have name and logo suggestions, leave a comment (or send me an email).
