You are reading the wrong thing about clonezilla.  In disk image mode it 
will duplicate the partitioning for you and it knows enough about most 
filesystems to just copy the used portions.  There are options to just 
take one partition if you want, but if you do the whole disk it will set 
up the partitions for you.  It understands LVM, but not multi-disk 
software raid.  I'd expect it to be faster than any other way to 
duplicate systems if you don't count downloading the iso and making your 
initial image copy from the master.

Clonezilla can also be network-booted if you have enough machines to be 
worth the trouble to set up (and it can clone windows and other linux 
distributions as well).  There is a companion project called DRBL that 
handles network booting and provides NFS storage for the clients to save 
and load images.
