I looked at that.  As I recall, the drive image of the dual-boot 
installation with maximum compression was over 20GB (the lion's share of 
that due to the Windows Vista partition -- I think I can probably still 
get my usual Lubuntu-only installation onto a single bootable Clonezilla 
DVD).  In any case, I remember that a 16GB drive would not do -- I would 
have to move up to a 32GB drive.
