* Forking cauldron tree

 update mageia-release and lsb-release for the new version. Then rebuild
 drakx-installer-binaries, drakx-installer-images, drakx-installer-rescue,
 drakx-installer-stage2.

 fork the cauldron tree to the new release tree :
 valstar# ./fork-distribution /distrib/mirror/distrib/cauldron /distrib/newrelease/1

 Do the same on rabbit (to avoid downloading everything) :
 rabbit# ./fork-distribution /distrib/mirror/distrib/cauldron /distrib/newrelease/1
