Read only filesystem size issues.

I looked at the pwl_target_load script. The filesystem size calculated is
compared to the total device space available. Since both /root and /home
are placed on the target device both need to be considered when
calculating if the extracted system will fit onto the target device.

I did however miss to deduct the sizes of /etc, /var and /dev from the
root partition. Those three directories are placed in a ramdisk and the
size of the compressed ramdisk is already taken into consideration when
calculating the root filesystem sizes.

TTYL,
Adi
