Informal Wiki Setup -Diff-

You can replace the '/sys/lib' with '$home/lib' in the following configuration if you don't have write access or don't want to run wikifs as bootes on a cpu server.

mkdir /sys/lib/wiki.sample
{cd /sys/lib/wiki && tar cp .}|{cd /sys/lib/wiki.sample && tar xT}
mkdir -p /usr/web/wiki/sample

cd /usr/web/wiki/sample 
hget -o create.html http://plan9.bell-labs.com/wiki/plan9/create.html

See httpd(8) -- (more documentation on setting up httpd would be nice)

You'll need to edit /lib/namespace.httpd in at least the following way:

find the current wiki reference in /lib/namespace.httpd

# mount -b #s/wiki.plan9 /usr/web/wiki/plan9
mount -b #s/wiki.sample /usr/web/wiki/sample

modify create.html for your liking -- bellow is a diff on changes for the sample

cpu% diff create.html /sys/lib/wiki.sample/create.html
3c3
< <title>Plan 9 Wiki: Create a new page</title>
---
> <title>Plan 9 Sample Wiki: Create a new page</title>

< <input type="hidden" name="service" value="plan9">
< <input type="hidden" name="base" value="/wiki/plan9">

> <input type="hidden" name="service" value="sample">
> <input type="hidden" name="base" value="/wiki/sample">

< </html>

> </html>

Make similar edits to /sys/lib/wiki.sample/edit.html

wikifs -p 666 -s wiki.sample -a tcp!*!wiki /sys/lib/wiki.sample
ip/httpd/httpd

You can now access your new site using Acme wiki instructions or a web browser with a url similar to the following:

http://localhost/wiki/sample/plan_9_wiki/

Additional details about resetting your base configuration still need to be addressed.
