I tried installing
http://remi.collet.free.fr/rpms/fc4.i386/cups-pdf-2.0.0-0.1.fc4.remi.i386.rpm.
The RPM has the following post-install scriptlet:
if [ "$1" -eq "1" ]; then
/etc/init.d/cups restart
( /usr/sbin/lpadmin -p Cups-PDF -v cups-pdf:/ -m PostscriptColor.ppd -E &&
echo Cups-PDF printer created
) || true
fi
With selinux-policy-targeted-1.27.1-2.11 in enforcing mode, the lpadmin
command fails with error:
lpadmin: add-printer (set device) failed: client-error-not-possible
In permissive mode, the install proceeds without problem.
The relevant audit.log entries are:
