I was only partly joking when I said that it would be cheaper to just ship folks a $200 PC than to try to support every Unix variant out there.
I for one took you completely seriously, sounded like a reasonable statement. Of course, I'm sure a lot of folks would sign up to try it out if we advertised our solution!
Anyway, I already wrote a tclsh program that works for linux. The only thing missing for the total newbie is a bootstrap script to install the installer.
As you said there isn't anything difficult in the task of installing the system, but my script gathers all the software and installs from scratch in about an hour (mostly postgres compile time). Still left is the boot up of AOLserver to fill out the form for OpenACS install.
The main problem with my program (besides the fact that I wrote it) is it does what you tell it, which could lead to errors, but if the install script is correct, it works. Unlike an installation document, an install script can be tested for correctness.
