# Script to upgrade a host, which is subscribed to an enterprise-internal
# mirror of the Novell update service, to SLE?10 SP1.
# It is assumed that the update tree has the structure that yup builds.

# 05 Jul 2007 Andreas Taschner
#
# Changelog :
# 01 Aug 2007 : Fixed typos in info messages
#               More informational messages in log about progress
#               Eliminate "...failed" messages on console when shutting down ZMD
#               Proactively kill zen-updater desktop task as it sometimes gets 
#               confused and abends
# 03 Aug 2007 : Add support for SDK
# 30 Aug 2007 : Add explicit installation of product-sdk10-sp1 patch to 
#               to ensure the product verion of SDK gets updated
# 31 Aug 2007 : Unsubscribe from the SLE?10-SP1-Online catalog after upgrade, 
#               but keep it in the list to preserve virtual SP1 installation source
# 05 Sep 2007 : Minimized the need for manual intervention to customize the script
#               Add extra restart of ZMD after stage 4
# 06 Sep 2007 : Syntax-check of $UPDATE_ROOT
# 19 Sep 2007 : v0.28
#               Change the way we check if zmd has settled (Bug 309861). Now we
#               check for pending services rather than # of available updates, since an 
#               up-to-date system would fail the first of these checks.
#               Added more checks on whether zmd has settled. Misc cosmetics.
#               Improved handling of rug errors in stage 5 and 6
# 02 Oct 2007 : v0.33
#               By default update the SDK if it is installed unless $UPDATE_SDK = NO
#               Verify existence of the various repositories (currently only 
#               checks for nfs and http based repos) and exit on errors
#               prior to adding services. Misc cosmetics.

# (not having the SDK at the same level as the OS can lead to problems)
# you must change
# UPDATE_SDK to NO.
