Getting ready for another release. 

During the boot stage the filsystem type was used to determine whether
to use the genext2fs (non-root) method or the normal method used by root.
Now the user type is used, this is better because it prevents conflicts
if a different filesystem type is chosen, or if a non-root user changes to a
different filesystem type in the filesystem box and forgets to change back
to genext2fs; however, it prevents root from using the genext2fs method,
which isn't a problem.  The sudo requirement for lilo is too much of a
requirement, and will be changed in future versions.

During the boot stage the filsystem type was used to determine whether
to use the genext2fs (non-root) method or the normal method used by root.
Now the user type is used, this is better because it prevents conflicts
if a different filesystem type is chosen, or if a non-root user changes to a

which isn't a problem. The sudo requirement for lilo is too much of a

Fixed another non-root boot/root bug. The info had it correct, but the actual
copy with genext2fs was being done from the wrong location. This has been
fixed.
fixed. This method may be ditched for a far better one in the near future.
Had some testing code which was providing the wrong value for $compress, this
made non-root booting fail for bzip2 because bunzip2 didn't exist in the
