I think the best thing for Mga3 is to both install journald and
upgrade rsyslog too by sticking it on install medias.

Then we add in Mga 3 release notes that for upgrades rsyslog
will be upgraded, but new installs will only have journald,
so people wanting / needing it _must_ install it manually.

And we also add the in the notes that we *might* obsolete
(but not remove from repos, to still keep it as an option)
it during upgrades in coming mga releases if journald gains
all the features needed to really replace rsyslog.
So we suggest people start trying to see if journald can
provide all that they need.

As a side note...
when journald was first introduced I had the "what for..."
reaction too as I was so used to grepping syslogs for
stuff I needed... :)

But now when I have gotten used to journalctl and the power
of it, I dont really need the old logs anymore :)
