if you are dealing with rsync you HAVE already partitions
where you copy things around - so there is nothing
to recognize

if wouldn't do this and stick with dd / disk images and use gparted
to resize partitions because if i clone machines i want to have
all UUID's the same which matters in border cases like diks usgae
widget of KDE in case you sync two of your machines regulary and
because any LVM/RAID whatever IDs and there configs are 100% sane
