Given the change happened a significant time ago and your the first to hit an issue and its regularly tested from a range of versions its hard to see most users being effected although most users are also now on btrfs and would have been able to roll back.
Most on brtfs?
Yeah, its been the system default for ages now and most users don't change the defaults.
I suspect that a random survey would surprise you, about that particular default :-D And in theory, users of TW are more learned and would know how to change defaults. ...
Asked why compression encoding was changed, not why compresssion is used. gzip and bzip2 were both supported previously. I might have even expected xz at some point, but I've seen no measurements on speed or %compression for one that went into rpm, nor have I seen anyone using it outside of rpm.
Well it was changed for the same reason it's used :-) someone did the measurements and the newer form of compression that are only supported in the latest versions of rpm make smaller binaries and or decompress / compress data faster, at some point there was a thread on factory discussing this and showing some benchmarks so the change to the newer compression form was adopted, unfortunately significantly older forms of rpm don't support this but we made sure it worked in still supported distros.
Yes, I remember the discussion. I think that there was also a consideration about the CPU time it took to compress them: some algorithms compress a lot but also are very CPU costly. ...
---- Maybe once in place, but moving established systems to that point -- it would be nice if it was handled a bit more gracefully.
But opensuse no longer has a fix-on-boot & continue recovery system which I'm more used to. Others may not notice the difference.
I know these days we have a rescue system based off busybox but fortunately I've never had the need to use it maybe because on all the very rare times something has broken on my system i've been lazy and rolled back to the previous snapshot and waited for a fix before upgrading again.
Me uses an external rescue image to solve issues. -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)
