It's been a while, but I'm almost ready to release Yaifo for OpenBSD 4.7. I have tested my updates with i386, amd64, macppc, and alpha. I consider those architectures "stable". I know sgi and landisk aren't working. I don't have a sparc, so I can't test that. I have to replace a disk in my sparc64, so I'll test that when I can (I expect to have ramdisk space issues).
If you are able or are willing to test sgi, landisk, sparc, or sparc64, test reports and diffs are welcome.
The beta release can be downloaded from SourceForge.
