With all due respect, this might be utter bullshit, but is at least
[citation needed]. I have yet to see a failing pid 1 (be that sysv,
upstart or systemd). Acquiring data on failure modes of any of those
systems appears like a difficult task and d-devel might not be the best
place to discuss that.

The problem is not that people disagree on that a good init system is
needed, but about what good comprises. Some people believe that a good
init system should run on all supported architectures including
kfreebsd-*. By this particular metric sysv init still outperforms
systemd. In fact for every combination of init systems you will find a
metric where one outperforms the other.

And this is where choice makes sense IF the benefits outweigh its costs.
Unfortunately that if is a very tough question.

Let me therefore direct a question to those in favour of a switchable

What are the benefits of using shells other than dash for /bin/sh? (as
opposed to other viable mechanisms to select a shell such as the shebang
of your scripts)

Answers I've seen so far:
 * Backwards compatibility with systems that still use bashisms.
 * Users who want to choose /bin/sh to satisfy some belief in

Summaries or references to previous discussion appreciated.
