RHEL5 kickstart overwrites USB

[Jason Edgecombe]

Hi There,

I use the following snippet in my kickstart files:
======
%include /tmp/part-include

%pre
#----- partitioning logic below--------------
# pick the first drive that is not removable and is over MINSIZE
DIR="/sys/block"

# minimum size of hard drive needed specified in GIGABYTES
MINSIZE=23


ROOTDRIVE=""

# /sys/block/*/size is in 512 byte chunks

for DEV in sda sdb hda hdb; do
  if [ -d $DIR/$DEV ]; then
    REMOVABLE=`cat $DIR/$DEV/removable`
    if (( $REMOVABLE == 0 )); then
      echo $DEV
      SIZE=`cat $DIR/$DEV/size`
      GB=$(($SIZE/2**21))
      if [ $GB -gt $MINSIZE ]; then
        echo "$(($SIZE/2**21))"
        if [ -z $ROOTDRIVE ]; then
          ROOTDRIVE=$DEV
        fi
      fi
    fi
  fi
done

echo "ROOTDRIVE=$ROOTDRIVE"

cat << EOF >> /tmp/part-include
bootloader --location=mbr --driveorder=$ROOTDRIVE
clearpart --all --drives=$ROOTDRIVE --initlabel
part /boot --fstype ext3 --size=300 --asprimary --ondisk=$ROOTDRIVE
part /tmp --fstype ext3 --size=5000 --ondisk=$ROOTDRIVE
part swap --size=2000 --asprimary --ondisk=$ROOTDRIVE
part /usr/vice/cache --fstype ext3 --size=1500 --ondisk=$ROOTDRIVE
part /home --fstype ext3 --size=100 --grow --ondisk=$ROOTDRIVE
part / --fstype ext3 --size=20000 --grow --maxsize=30000 --asprimary
--ondisk=$ROOTDRIVE
EOF

========
The script in %pre avoids removable drives such as USB.

I hope that helps.
