at L60-71, if grep fails to find a match it will throw exit code 1 and the if will fail
I've changed to

                grep \
                    -qsE '''kernel\.unprivileged_userns_clone[[:space:]]*=[[:space:]]*0''' \
                    /etc/sysctl.d/* ;
                echo $?

grep will be silent, printing no output and the result of the command will be consistent with the output pattern 1 if fail, 0 if it found the line on sysctl.d/*
