Live USB sticks with persistence

[gold_finger]

@bugfree,

Not sure why you're having a problem creating persistence.  I just ran a test doing the steps I outlined above and had no problems.  Here's what I did.

• On my LL 2.0 desktop machine I used GParted to create a 2GB FAT32 partition and a 30GB Ext2 partition (no label on Ext2 at this point) on a 32GB USB stick.  (USB stick is approx. 1-yr old Kingston.)
  
• Using UNetbootin, created live Mint Xfce 17.1 (64-bit) USB directing it to use the 2GB FAT32 partition.  The ISO file is approx. 1.6GB, so made a persistence file of approx 400MB to take up rest of 2GB size.
  
• Booted the live USB on different computer to make sure it worked after initial creation.  It did work (including persistence).  Shutdown live environment; then plugged it back into my LL desktop machine.
  
• Opened GParted again and labeled the Ext2 partition as "casper-rw".
  
• Mounted the 2GB FAT32 partition on the USB and opened it with file manager.
  
• Found and deleted the "casper-rw" file on the FAT32 partition.
  
• Unmounted and ejected the USB.
  
• Booted other computer again with the USB.
  
• Worked again and this time persistence showed it was approx. 30GB instead of 400MB.
  

So, for me everything seems to work fine.  (I didn't try to resize the USB partitions in GParted -- that probably still fails.  But creating them from scratch works fine.)
