zstd based preinstallimages going forward
Hi all, today's openSUSE Build service (OBS) deployment brought an exciting change: going forward preinstallimages will be compressed using zstd rather than gzip, which improves decompression speed by ~ factor 4 and thereby lowers setup time for builds both locally as well as server side. There is a small chance that you're no longer able to do local builds, especially if you run on very outdated openSUSE or SLE distributions (older than 15.2) or non-SUSE based ones. Please let me know how you are affected. if there is significant fallout we might have to craft up more compatibility. The easy way out is to use --nopreinstallimage as a build option or setting `no_preinstallimage = 1` in your oscrc as an option. it probably is advisable to do that anyway as the preinstallimages are rather big to download and often it is quicker to just cache the individual rpms (its a bit of a tradeoff between time-to download and time-until-build-starts) If we're missing usecases or combinations where that turns out to be a problem, feel free to let me know. Greetings, Dirk
