Live usb creation with persistence

[intelliant01]

Document the process for live usb creation with persistence as it is a much desired feature.

Ref: RechercheTech/mss#38

@geets04 Please verify this and then document it.

These steps should have worked -

1. Connect to MSS via remmina / Admin-Desktop + mssadmin login
2. Open Terminal
3. sudo su -
4. export cowsize=1000M (This is the size of the persistent storage area on the pen drive. Default is 500M)
5. Try both of these independently and see if the bootable pen-drive is being created -
   a. live-fat-stick --ubuntu-persistent /home/mssadmin/Li-f-e.iso /dev/sdXY
   b. live-grub-stick --ubuntu-persistent /home/mssadmin/Li-f-e.iso /dev/sdXY
   Where X is the device identifier such as a,b, c... and Y is the partition identifier such as 1, 2, 3,... for example: /dev/sdb1

There seems to be some problem since it did not work last time we tried during a demo.

New image has the fix, for the old mss, either of the following should work

ln -s /home/mssadmin/Li-f-e.iso /home/mssadmin/Linux-for-Education-16.04.3-amd64.iso
live-grub-stick --ubuntu-persistent /home/mssadmin/Linux-for-Education-16.04.3-amd64.iso /dev/sdXY

or

cd /usr/bin/
rm live-grub-stick
wget https://raw.githubusercontent.com/cyberorg/live-fat-stick/master/live-grub-stick
chmod +x live-grub-stick
live-grub-stick --ubuntu-persistent /home/mssadmin/Li-f-e.iso /dev/sdXY

Tried above process using
live-grub-stick --ubuntu-persistent /home/mssadmin/Li-f-e.iso /dev/sdXY .
But cow-folder created in usb shows 500 Mb size even after using export cowsize=1000M during installation.

And when tried with
live-fat-stick --ubuntu-persistent /home/mssadmin/Li-f-e.iso /dev/sdXY
terminal shows error with "can't create a cow file" and persistence didn't apply with above command.
Is persistence possible with live-fat-stick ? as it is available in Help .

Pastebin the output of:
export cowsize=1000M
bash -x /usr/bin/live-grub-stick --ubuntu-persistent /home/mssadmin/Li-f-e.iso /dev/sdXY

and
export cowsize=1000M
bash -x /usr/bin/live-grub-stick --ubuntu-persistent /home/mssadmin/Li-f-e.iso /dev/sdXY

You posted on wrong issue(RechercheTech/mss#38 (comment))?

That does not look like new installation, on old install follow: #51 (comment) replace live-grub-stick with live-fat-stick to update that script
