Fetching data for a debuginfofs server
1) Edit /etc/debuginfofs.conf (if needed)
2) run debuginfofs-mirror REPO [REPO...]
 - Note: if you're on EL5 and you want rawhide/F11 debuginfo you might need
   to install a newer python-hashlib. See here:

Running the debuginfofs server
1) service debuginfofs-server start
- You might want to edit /usr/share/debuginfofs/dav-debuginfo.conf
- If you're running SELinux you'll need to allow httpd to access port 3309.
  The package %post script handles this, or you can do it yourself:
  /usr/sbin/semanage port -a -S targeted -t http_port_t -p tcp 3309

Some rough stats about disk usage:
- F10 i386+x86_64 full debuginfo stats:
  - debuginfo data (.debug files): ~100k files, 73GB
  - sources: ~2.2m files (!), 38GB
- F10+Rawhide, i386+x86_64:
  - debuginfo data: ~200k files, 111GB
