I currently host my RadiantCMS instances at Webfaction and the
experience has been quite wonderful. However, it could be even better if
Webfaction had an install script that set it up for you. The folks at
webfaction would love to create an install script if enough people ask
for it. Or better yet, someone could create one (their API is pretty
simple, thinking about doing it myself).
If you host at Webfaction, then by all means request it in a ticket or
in the forum. Thanks.
