expr(1) has been obsolete for more than two decades, you can just use

I don't know why kiwi's initrd calls an external tool for it either :)

haveKByte=`cat /proc/meminfo | grep MemFree | cut -f2 -d:| cut
-f1 -dk`
- haveMByte=`expr $haveKByte / 1024`
- haveMByte=`expr $haveMByte \* 7 / 10`
+ haveMByte=$(($haveKByte * 7 / 10240))

cat has been obsolete for these kind of tasks, you can just use

grep MemFree /proc/meminfo
