# This script mirrors a base distribution from the opensuse.org 
# Build Service. You can use it to create initial base projects
# in your build service to build for.
#
# This script does mirror only build packages, not the sources. 
# Yes, it is just a fast hack for now, please submit cleanups :)
#
# Missing: * switch off building of mirror projects
#            (baserepos are disabled anyway by default)
#          * mirroring of package meta data, needed to build packages
#          * use mirrors by default for downloading

I skipped the download of packages that already exist.  I did not
check wether those files were correctly or completely downloaded

When you restart the scheduler it will tell you about broken packages
in it's log file in /srv/obs/log/ .  Simply remove the broken package
and re-run this script to update the broken file.

The paranoid may run rpm --checksig, like this:
  rpm --checksig #{destinationdir}/*.rpm

"
  end

# fix ownership in case this script did run as root

Mirroring succeeded :)
Please restart the scheduler to rescan your projects:

rcobsscheduler restart"
