Wellll.... I was thinking it was preventing the container from booting
properly as we booted our host with "rescue" in the command line, but
thinking about it more, the container seems to make it to multi-user
target just fine... it should be defaulting to graphical.target (that's
what the default.target symlink points to at least) but that doesn't
kick in... not looking into why but I kinda *want* it to be
multi-user.target for debugging anyway, so not too upset about that.

So I think my "problem case" might actually be invalid, but glad I came
up with a nice idea in the process ;)
