Re: Introduction to a new SIG for creation of Live DVD



Deltaisos are capable of saving roughly half the download size in
going from Fedora N to Fedora (N+1), but only work for installation
images, not live images.  Is there any form of delta compression for
live images which is competitive with this?

It hasn't been productized, but approximately:
   unsquashfs  old-Live.img  old-Live.tree   # local  ("slave")
   unsquashfs  new-Live.img  new-Live.tree   # remote ("master")
   rsync  remote:new-Live.tree  local:old-Live.tree   # "delta compression" happens here
   mksquashfs  old-Live.tree new-Live.img   # local
