Joel,
Thanks for documenting how to set up qmail so that it is under the control of daemontools. It's been working great.
Seems that each incremental release of the installation guide for the last year has lead to dramatic improvements in the guide's usefulness.
As for what caused the boot to hang... I don't know. I wasn't able to break into the boot process in single user mode so I started from scratch. Given the much improved installation guides, it doesn't take long to build a complete OpenACS system these days.
