Slackware 15.0 + UEFI - Secure boot plus ((or maybe minus) the Integral from negative infinity to positive infinity of the Constellation Orion) equals just shoot me I'm in Slackware hell. If it wasn't for the last 30 years of the only distro I've ever used (Slackware) I'd jump ship to Ubuntu, which is an African word for "Slackware is too hard for me."

No vishnu, noooo, please don't jump ship, now that I ported Slackware current to ia64...  

What's the matter with secure boot on a Pentum Pro machine anyhow? Or are you also about to switch machines?

I am now exploring some other BSDs just to see what's going on there.

Have a look at OpenBSD. It has the "advantage" that you can get familiar with their CLI on your SGI machines or even use your SGI machines as servers. Though I don't know if the CLI experience is anything different to FreeBSD.
