[Cin]bld_prepare.sh script and Suse Slowroll

Terje, if you replace single [ with two [[ in this suse section of script like this - if [ ! -f /usr/lib64/libtermcap.so && ! -L /usr/lib64/libtermcap.so ]; then + if [[ ! -f /usr/lib64/libtermcap.so && ! -L /usr/lib64/libtermcap.so ]]; then will it run zupper line as it should ? I only tested this on Slackware 15.0 with bash 5.3
