[Before]
public static function has_pdf_combiner() {
// Check we have a valid way to combine pdfs
$combiner = false;
if ($pdfunite = exec('apt-cache policy poppler-utils | grep Installed')) {
if (!preg_match('/Installed\: \(none\)/', $pdfunite)) {
$combiner = 'pdfunite';
}
}
if ($ghostscript = exec('apt-cache policy ghostscript | grep Installed')) {
if (!preg_match('/Installed\: \(none\)/', $ghostscript)) {
$combiner = 'ghostscript';
}
}
return $combiner;
}
[After]

}
if ($pgtune = exec('rpm -q ghostscript')) {
