PRACTICAL EXERCISE 13: CUSTOMISING A DEBIAN DISTRO WITH REMASTERSYS

GENERAL CONDITIONS
1- Deadline: 4-4-2014.
2.- Create a customized Debian ISO image.
3.- Create a USB Startup Disk with your customised Debian ISO image
4.- Boot your computer from your USB Startup Disk.

PRACTICAL EXERCISE

PART 1: INSTALLING AND CONFIGURING REMASTERSYS ON DEBIAN
1.- Gain access as root user to the recently created DebUb virtual machine.
2.- Download a script called RemastersysonDebianInstaller.sh. Run the following command:

wget http://www.collados.org/asix1/m01/tu1/RemastersysonDebianInstaller.sh

3.- Add the execute permission (only for the root user) to RemastersysonDebianInstaller.sh.
4.- Run RemastersysonDebianInstaller.sh.
5.- Check if Start Remasterys has been properly installed. Check if the new entries Remastersys Backup, Remastersys Grub Restore and Remastersys USB Startup Disk Tool are available in the menu : Applications --> System Tools.
6.- Run Remastersys Backup and select the option Modify. Modify the "Live ISO filename" entry. The new value will be bootusb.iso.

PART 2: CUSTOMISING YOUR DEBIAN
1.- Install the following packages: apache2, geany, build-essential, and gftp.
2.- Create a new user called clot, whose uid is 1001, member of the users group, whose home directory is /home/clot, whose shell is the bash program, and whose encrypted password is Clot2014.

PART 3: MAKE A CUSTOMISED DEBIAN ISO IMAGE
1.- With the help of Remasterys Backup, create a ISO image file with a customized version of your operating system including your personal data. Select the option "Backup" It may take some time to complete the process.
2.- Check if bootusb.iso has been created on /home/remasterys/remastersys.
3.- Remove any file on /home/remasterys/remastersys except bootusb.iso.

PART 4: CHECK IF THE NEWLY CREATED CUSTOMISED DEBIAN ISO IMAGE WORKS PROPERLY
1.- Working with your host machine: Create a new folder called sharing inside the VirtualBox VMS folder.
2.- Working with the VirtualBox pannel control: Add sharing as a shared folder of your DebUb virtual Machine.
3.- Working with your DebUb virtual machine: a) Create a new folde called /mnt/host_sharing b) Mount sharing running the commnad: mount -t vboxsf sharing /mnt/host_sharing.
4.- Working with your DebUb virtual machine: Move bootusb.iso to /mnt/host_sharing.
5.- Working with your host machine: Check that bootusb.iso has been created on sharing.
6.- Power off your DebUb virtual machine. Add bootusb.iso as a new iso image. Start DebUb with the newly installed iso image. Check if DebUb boots with bootusb.iso. If it works, you can jump to the next part.

PART 5: COPY A CUSTOMISED DEBIAN ISO IMAGE TO A USB DRIVE AND CHECK IF IT WORKS PROPERLY
1.- Boot again DebUb with the hard drive DebUb.dvi.
2.- With the help of Remastersys USB Startup Disk Tool, copy your newly created ISO image file bootusb.iso to a USB drive plugged on your DebUb virtual machine.
3.- Eject the USB drive from your virtual machine. Power off your virtual machine. Boot your virtual machine with the customised bootable version of Debian installed on a USB drive.
4.- Power off your host machine. Boot your host machine with the customised bootable version of Debian installed on a USB drive.
