Where would "further discussion in 1-2 years" rank for you?

What I suggested earlier in this discussion was not that you vote for
keeping sysvinit forever, but:
  * jessie will continue to use sysvinit, and the TC will re-evaluate
    the situation after the release of jessie


As time passes, the kernel<->systemd interface will become more
stable since new features systemd wants like kdbus will already
be in the kernel, reducing potential upgrade problems.

It will also become more clear how exactly systemd is evolving and what 
exactly the consequences are for Debian in areas where Debian differs
from other distributions. 


And in my opinion the worst case would be that Debian switches init 
systems in jessie and then again in jessie+1.

OpenRC looks too WIP and with an unclear future for me for switching
to it for jessie.

Upstart is mature, but I would be cautious since Canonical might decide 
at some point in the future that systemd is better and abandon upstart.
I am not seeing a big probability of that happening, but it is a risk.


If you are convinced that any of systemd/OpenRC/upstart is the best 
option for Debian then vote for it, but no matter where you vote
"further discussion" it is unlikely that there will be significant
new arguments in the immediate future - and it would therefore be
better to wait 1-2 years until the further discussion happens.

When staying with sysvinit is only the stopgap solution for jessie, then 
significant upstream development would not even bring any advantages.
