the "zypper.log" output in updates.txt is basically useless... It only contains output from commands run by the supportconfig itself.
It does not provide historical info and as such just takes space in an already large file.
I suggest an extra supportconfig flag that will gather zypper.log and/or the additional zypper.log-*.xz files.
Or just collect the full zypper.log as a standalone file and not included in updates.txt.
honestly, it would be great to break out all log files into separate files and not clutter their respective .txt file.
