• What are packman/supplementary updates?
  Fou4s is capable of downloading packages from other sources than YOU. You can specify an rsync server (sorry - no HTTP/FTP!), and fou4s will search all RPM files there, generated patch descriptions and process them like normal updates. See /etc/fou4s.conf and look for the commented "Server=" lines as examples. To answer the original question: Packman infos can be found at http://packman.links2linux.de/. Supplementary updates are from SuSE. See also fou4s(1) for information.
• A script was found, what shall I do?
  Currently the script-"packages" provided by SuSE are used to download truetype fonts or nvidia drivers, that can't be installed from CD because of legal issues. Scripts require interactive mode of fou4s, because fou4s can't know if you really want to install nvidia drivers or truetype fonts. You can also choose not to run the script using the skip (s) option when running fou4s --interactive. If you want to run the script, although it was skipped before, delete the appropriate line from /var/cache/fou4s/skipped-packages.$HOSTNAME.$suseversion
• WARNING: different versioning scheme: foo: 1.2.1 > 1.0 = true
  This means, that the structure of the version from the old package is different from the new package. The true or false indictates the guess of fou4s, if the other version number is newer or not. If you get this warning with "= false" at the end (and fou4s guesses right), you can put the specific package on the IgnoreList in fou4s.conf to suppress the Warning.
• [: too many arguments
  This is a bug in fou4s. Please send me the output of bash -vx fou4s --ri <your options> &>fou.log
• gpg: no valid OpenPGP data found. the signature could not be verified
  The fou4s build key was not imported into your keyring (or if you are running fou4s as root on SuSE >= 8.0: the RPM keyring). This should not happen, please tell me exactly how you installed fou4s!
