Does systemd have a historical record of its defect rate being significantly greater than that of the kernel/glibc?
I just checked Coverity scans, and the most recent defect densities appear to be:
kernel : 0.59
glibc : 0.54
systemd: 0.04
which actually looks pretty good for systemd. Is there some other analysis you're basing this off? Or are the current rates atypical, and systemd used to be a lot worse?
What are you basing that on?
