NANO_MEDIASIZE=`expr 4097802240 / 512` NANO_MEDIASIZE=`expr 4224761856 / 512` Those result with... expr 4097802240 / 512 4194303 expr 4224761856 / 512 4194303 >How-To-Repeat: Include "FlashDevice Sandisk 4g" in your nanobsd configuration file. Insert a few debugging print statements in nanobsd.sh where NANO_MEDIASIZE is used. When "/bin/sh nanobsd.sh -c nanobsd.conf" is run $NANO_MEDIASIZE always prints 4194303. >Fix: Use expr -e expr -e 4097802240 / 512 8003520 expr -e 4224761856 / 512 8251488 The man page for expr also states that if EXPR_COMPAT is set then expr -e is used. >Release-Note: >Audit-Trail: >Unformatted:
