Changing the default target depending on the use of the image isn't
really the same as forking systemd, and we're not making anything
incompatible.

Obviously the nuances of my sentiment were lost as it was transcribed to ASCII.

I'm advocating changing the default target to multi-user and then
patching the two recipes where X session scripts are packaged to also
set the target to graphical.  People switching to systemd who don't
use the standard X sessions (they roll their own, or don't use X, or
whatever) will notice quickly that the default target needs to be
changed, and can do it in their graphical startup recipes.

You're suggesting leaving the default target as graphical and changing
uncountable numbers of *image recipes* to override the default target,
the alternative being errors in the log.

So far "the community" disagrees on the approach here - we've had
vocal objections to errors in the log for any image, changing the
default target, and the other proposals.

We *do* need a way of changing the default target.  Do we at least all
agree that update-alternatives is a logical way of changing it on a
per-image basis?
