[9fans] rc-httpd cgi heredocs

[Danny Wilkins via 9fans]

(Sorry if the last message got through, misremembered m as new mail in nedmail and it forwarded the first message in my inbox)

I'm messing around with cgi scripts in rc-httpd to store my html templates, however when I try to execute them, the script
errors out because it can't open /tmp/herex..... . I assume herefiles are 'fake' and just throw a file in /tmp, but what do
I need to do to let cgi scripts use them? I'm invoking my script with the cgi handler and I don't see any special handling
for tmp in there.

Thanks,
Danny

Ended up getting a response on IRC:
This was because CGI scripts are run as none, who has no write permissions. It was fixed by adding a ramfs call to the script to make a none-writable /tmp
