→‎Linux instructions: Added MBR overwrite instructions

* Also, check to see that you do not already have an existing bootloader (such as GRUB) in the MBR of your stick. If you have not previously used this stick as a live boot, you can skip this step.

* Also, check to see that you do not already have an existing bootloader (such as GRUB) in the MBR of your stick. (If you have not previously used this stick as a live boot, you can skip this step.) To be sure that the USB stick's MBR is wiped clean, overwrite it completely using:

−

:~~#TODO: instructions.~~

+

: <tt>dd if=/dev/zero of=/dev/sdb bs=446 count=1</tt>

* Unmount the drive,<br>

: <tt>sudo umount /dev/sdb1</tt>

Line 54: Line 54:

: <tt>chmod +x livecd-iso-to-disk.sh</tt>

* Run it as root, making sure to pass the correct USB device and to set overlay and home size appropriately, depending on the stick size.

−

sudo ./livecd-iso-to-disk.sh --overlay-size-mb 300 --home-size-mb 160 --delete-home --unencrypted-home soas-beta.iso /dev/sdb1

+

sudo ./livecd-iso-to-disk.sh --overlay-size-mb 300 --home-size-mb 160 \

+

--delete-home --unencrypted-home soas-beta.iso /dev/sdb1

The Linux installation has the advantage of allowing a persistent /home/liveuser folder with the <tt>--home-size-mb ''NNN''</tt> option. This feature would allow you to update the OS image while keeping the user files (by running the script against your existing installation but <u>leaving out</u> the --home-size-mb NNN option).

* The <code>--unencrypted-home</code> option prevents password protection and encryption of the /home/liveuser folder. This releaves overhead on the compressed sqaushfs, and should be more robust to file system failures (outside of security).
