Thanks Olivier.  Although this question wasn't asked, I'd add a reason not 
to run as the web/ftp service account, which is to ensure that the web/ftp 
service is unable to access the content if it isn't world readable; eg 
when content is made available to mirrors before public announcements, and 
a permission bitflip is used to make the content available on the release 

Ironically, I do run rsync --daemon as root for a few reasons:
- use chroot=true
- listen on port 873
- specify per-module uid, gid

Admittedly, I could manually chroot the daemon to the entire mirror 
tree before running it as a regular user, and I could do some port 
forwarding or iptables stuff and run rsyncd on a high port, and use a 
common nobody-like account for all modules...

What do you guys do?
