Feedback

To avoid using the 'bc' binary, which might not be installed (and isn't by default) on a RHEL system, it would be better to use shell builtin features for arithmetic comparison and string manipulation:

Replace
if [ $(bc<<<"$VERSION_ID < 9") = 1 ]
by
if [ ${VERSION_ID%.*} -lt 9 ]
in the install script. (And similar for similar occurences in the script.)

Kind regards,
Daan
