When thinking about your goal again it is possible to skip this 
rsync/tar part completely and make jffs2 image from you modified 
filesystem directly on your device. The 'remount somhere else' trick is 
still needed to get rid of /proc /dev/ and /sys filesystems. But 
slightly better and safer way is to clone it to mmc and boot from it 
prior to some advanced modifications. Also when using live system 
directly you may include some temporary unneded files or even have bad 
luck and include some files partly written by running system (like gconf 
xml files).

BTW, sumtool arm binary is now included in the initfs flasher archive.
