[Zope] user Nobody?

Did I just read somewhere that beginning with a recent Zope release that the server no longer runs as user Nobody (for security reasons)? I've read so much stuff on Zope in the last week that I don't remember where I saw that or what it now runs as. Assuming someone gives me that name (please?) does that mean that the install HOWTO is already out-of-date (last modified 1/17/2000) and I need to substitute the new name for everywhere the HOWTO says "user nobody"? Or do I still follow the HOWTO to the letter? I'll be using 2.1.2 on LinuxPPC (Python 1.52). Many thanks! Darren Addy University of Nebraska at Kearney
