Re: Detecting a previous install

I would suggest that the user should think twice if there is anything on the drive, not just a file or directory. Our standard practice is to only kickstart completely new drives, so anything with an existing partition is bad news. You could make this die, or provide and opt out, as below (which keeps me from having to wipe test boxes before kicking). This works on EL-3 and EL-4beta:

# change to tty3 and check for partitions
chvt 3
exec < /dev/tty3 > /dev/tty3 2>/dev/tty3

# check
sleep 2
echo "Checking for existing partitions...\n"

FDISK=`which fdisk`
if [ `$FDISK -l | grep "^/dev" | wc -l` -ne 0 ] ; then
sleep 1
echo "Whoa! This server has data partitions!!\n"
while true; do
echo "If you wish to continue with kickstart, type -> YES <- :\n"
read answer
case $answer in
YES ) echo "\nContinuing with kickstart...\n" ; sleep 3 ; break ;;
* ) echo "\nHuh? Let's try again...\n" ;;
echo "Found no partitions - moving right along...\n" ; sleep 3

# move back to tty1 and continue with install
chvt 1
exec < /dev/tty1 > /dev/tty1

Kind Regards,
