Sad. I've seen supposed benchmarks showing the benefits of other
virtualization (FULL v12n) approaches over UML, but I've never
believed them. The default UML images opened up xterms as tty
devices. I didn't use those; I made ttys elsewhere, or even used a
system tty chown'ed.

I thought UML was a pretty nice idea. Makes more sense to me to run
Linux on Linux rather than having to do full hardware v12n. To me,
the subjective "feel" was fine. I ran servers in the UMLs. They
didn't seem sluggish.

My major UML project was a virtual DMZ. Really cool thing: boot up
one physical machine connected to the Internet, but it had no
services exposed to the Internet ... yet it was a full-service mail
and Web and VPN server, plus Samba and other services on the LAN.

My project died due to funding (it was sold to a customer without
proper consideration of development costs, and I declined to continue
development for free.)

Sometimes what the world chooses is not the best thing. This is not
the only occurrance of that happening in the computing world.

Thanks, Jeff; you were right, it *was* fun.
