Root filesystem access

1 Manually make root filesystem writable

On r700, per default the root filesystem ('/') is read-only.

To change it to writable, remount the filesystem with different settings.
Telnet to the box, login as root and remount in read-write mode.

/bin/mount -o remount -w /

2 Automatically make root filesystem writable

After reboot of the system, the filesystem is read-only again. Seems like modifying /etc/fstab does not really help, / is still mounted read only
Solution is a script that remounts automatically on boot.

Create a script making the root fs writable on boot, e.g. via 'vi'.

Filename: /etc/init.d/S20makeRootDiskRW

#!/bin/sh
#
# This script changes the root disk mount option, to make it writable
# (default is read-only)
#

start() {
        echo "Starting remounting root read-write..."
        /bin/mount -o remount -w /
        echo "Remounting root read-write completed."
}
stop() {
        echo "Starting remounting root read-only..."
        /bin/mount -o remount -r /
        echo "Remounting root read-only completed."
}
restart() {
        stop
        start
}

case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  restart|reload)
        restart
        ;;
  *)
        echo $"Usage: $0 {start|stop|restart}"
        exit 1
esac

exit $?

To test, simply execute 'reboot' on the command line, the cube will reboot.
