Just a brief brainlightning... 1) enable keeppackges for all repos (needs a lot of space) 2) create a snapshot (hardlink/copy) of /var/cache/zypp/packages at any point of time 3) use 'zypper dup --repo anysnapshot' with solver.upgradeRemoveDroppedPackages = true to install (downgrade/upgrade) from that snapshot and remove any others Could this be an acceptable solution? It does not roll back configuration and other stuff, but such type of rollback is also desired. https://bugzilla.novell.com/show_bug.cgi?id=506701 -- cheers, jano Ján Kupec YaST team ---------------------------------------------------------(PGP)--- Key ID: 637EE901 Fingerprint: 93B9 C79B 2D20 51C3 800B E09B 8048 46A6 637E E901 ---------------------------------------------------------(IRC)--- Server: irc.freenode.net Nick: jniq Channels: #zypp #yast #suse #susecz ---------------------------------------------------------(EOF)---
