Just tested now by copying /usr/share/clamav/clamd-wrapper from the 
old installation to the new.

First problem:

	Mar 13 18:49:50 asav clamd[23281]: Can't save PID in file /var/run/clamd.amavisd/clamd.pid

(actually the same problem with old clamd-installation). So i manually 
created this directory, and things seems to be working.

Yes.

.. and if we can get in the /usr/share/clamav/clamd-wrapper, running
the virus-scanner as amavis instead becomes trivial.

clamscan is waay too slow on a busy mailserver.

1 -  Add back /usr/share/clamav/clamd-wrapper to the clamd-package + possibly
     the README-file /usr/share/doc/clamav-server-0.96.1/README which explains
     how to set up individual clamd-instances:

	http://blag.tanso.net/code/clamav.spec
	http://blag.tanso.net/code/clamav-0.97-4.el6.src.rpm

     It's maybe not pretty to put this in %{_prefix}/share/clamav/, but IMHO it's 
     needed for compatibility with older packaging and existing installations on
     EL4/5.

2 -   Modify amavisd-new from f14 to create the directory /var/run/clamd.amavisd
      (it's already adding the service "clamd.amavisd" which use this directory).

3 -    Make amavisd-new not use "PidFile /var/run/amavisd/clamd.pid" in 
       /etc/clamd.d/amavisd.conf, since it's using the wrapper which overrides
       this pidfile anyway.

I'll get #2/#3 done as well, but would appreciate if someone could sponsor
me as a fedora maintainer, so that can also get this submitted to EPEL properly.
