If the cache can be used the clicfs is mounted with some cow file for write operations (5GB fixed at the moment) and the packagemanager only has to install the rest which is not already part of the cache if there is no cache kiwi builds it. It uses the patterns and the package list of the config.xml and build a cache for each of these groups. Especially the patterns are re-usable at any time which works great it's possible to have a cache server with a bunch of clicfs cache files and re-use them for the different kiwi --prepare operations. We plan to use that inside Studio but it could also be interesting for the preload department ..let's see -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
