atd.service and exim4.service do use DefaultDependencies=yes, so they
should be ordered after local-fs.target (via After: basic.target ->
After: sysinit.target -> After local-fs.target)


What is quite odd is the following, I'm looking specifically at Unit
local-fs.target from David's log:


Unit local-fs.target:
...
	Requires: var.mount
	Requires: tmp.mount
	Requires: home.mount
	Requires: -.mount
...
	After: local-fs-pre.target
	After: systemd-remount-fs.service
	After: home.mount
	After: tmp.mount
	After: systemd-fsck-root.service
	After: -.mount


There is no After: var.mount here!

Does anyone have an idea, what's going on there?
