New description:

 If you run a fast relay, you will end up using more than the default
 1024 file descriptors. Currently we point people who run relays to
 https://www.torproject.org/docs/tor-doc-relay.html.en and hope they
 read through to item #14.

 Debian, on the other hand, has a clause in the init script:
 https://gitweb.torproject.org/debian/tor.git/blob_plain/HEAD:/debian/tor.init
 that sets MAX_FILEDESCRIPTORS based on how many file descriptors are
 available on the machine, before it launches the Tor process.

Comment:

 Replying to [comment:2 katmagic]:
 > Enrico fixed this.

 Not well enough, I think. 4096 is better than 1024, but still not enough
 for fast relays, which sometimes use 10000 or more file descriptors. So I
 think it remains the case that you can't run a fast relay with Fedora's
 RPM.

 Here's a link to the Red Hat init script that our RPM uses:
 https://git.torproject.org/tor/contrib/tor.sh.in
 which already has this feature sorted out.
