Zypper dup migration from sle11-sp3 to sle12

an idea by oertel

During all of sle10 and sle11 it was possible to do a migration via zypper dup from one to the next service packs (and with some care even from sle10 to sle11). Due to some dependency problems this is currently not possible from sle11-sp3 to sle12. A official upgrade via installation media would blow up our nice small jeos installations from 300 to over 900 packages, which is undesirable as well. Currently I'm trying to get this running via a sle12 rpm source built on sle11 (plus some dependencies), next step is probably to get enough of libzypp and yast parts, not sure yet where exactly this is heading.

legacy full tree creation

an idea by oertel

some developers have been missing the old-style full trees for current products (sle12). try to reuse existing code to create these trees without wasting disk-space by using hardlinks

SLE-15 virtualization server tuning - make it faster

an idea by oertel

Investigate on our virt setup. Some things we found with sle12 might no longer be true, new I/O schedulers exist, network setup might have room for speedups as well.

extend netapp-harvest to also collect space usage data directly

an idea by oertel

currently netapp-harvest only pulls performance data (as seen on http://netapp-grafana.suse.de/ internally)
