16Mb of RAM will do okay on open once you build a 'minimal' kernel image. Disk space can be an issue, I've been working on making OpenBSD fit nicely into a 64Mb ATA-Flash disk.


The nice thing about rebuilding the kernel on an OpenBSD box is that it's very easy to build your new 'bsd' kernel file one a completely separate box of the same architecture, then just copy over this one file to the destination box. The same trick under FreeBSD is only slightly more difficult.

My primary 'dstumbler' test box is a 486, I've built a new kernel on this box exactly once, just to prove to myself that it was possible. Since then, I've built the new kernels on a P3/800, and of course it's a bad idea to do kernel builds on a FLASH drive.
