The very definition of "supporter" implicitly contains selection bias.
I daresay one cannot be an unbiased supporter and a human being at the
same time. Thus what you say here reads to me like a tautology.
Pointing to various events is all well and good (e.g. the stress2 panic
for DragonFly, unplugging mounted USB storage devices from FreeBSD), and
I understand the need for advocacy and challenge among various
supporters of projects...but I am keenly interested in some sort of
objective metric for stability beyond stress test panics and unfixable
Does an objective metric of stability actually exist? ( If you say
"uptime" I'll take that as a "no" ;) ) If it does, I would really like
to learn what that metric is. Do you know of any current
low-project-bias work that has been done in this area?
Thanks in advance. :)
