The poldecond program, which is part of the most recent slat distribution, was intended to help with this problem. It removes conditionals by generating statements based on the initial boolean values. Thus, tools that have not been updated to accept boolean conditions, such as slat, can be used with a policy file that contains booleans as long as the file has been preprocessed using poldecond.

The poldecond program is part of the slat sources stored in the selinux project CVS repository on SourceForge in the nsa module. We intend to make a tarball and an RPM of this version of the code available on a MITRE web server soon, although, our internal approval process seems to be greatly slowing us down. The slat change log says that the poldecond program was checked near the end of February!
