Creating the checkfs script

Create the /etc/init.d/checkfs script by running the following command:

cat > /etc/init.d/checkfs << "EOF"
#!/bin/sh
# Begin /etc/init.d/checkfs

#
# Include the functions declared in the /etc/init.d/functions file
#

source /etc/init.d/functions

# Activate all the swap partitions declared in the /etc/fstab file
#

echo -n "Activating swap..."
/sbin/swapon -a

# If the /fastboot file exists we don't want to run the partition checks
#

if [ -f /fastboot ]
then
        echo "Fast boot, no file system check"
else

#
# Mount the root partition read-only (just in case the kernel mounts it
# read-write and we don't want to run fsck on a read-write mounted 
# partition).

        if [ $? = 0 ]

# if the partition was unmounted cleanly the last time
