The more interesting information in all this is why RHEL is switching over
from upstart to systemd?

I mean we have an incentive to switch to something else because we can't
reliably fix stuff with sysvinit. But if upstart was satisfactory at that
level, what are the reasons why RHEL is switching again?

Maybe the security features discussed here are part of the answer, I don't

I believe that those who need those features just decide to use systemd
and won't "demand" those features to the upstart upstreams. In particular
when those features are of particular interest to people who are building
heavily customized systems (think embedded devices) and are not wary of
diverging from the defaults.
