Nope, I meant this code from mentioned commit:
@@ -243,8 +243,10 @@ int virSystemdCreateMachine(const char *name,
iscontainer ? "container" : "vm",
(unsigned int)pidleader,
rootdir ? rootdir : "",
- 1, "Slice", "s",
- slicename) < 0)
+ 3,
+ "Slice", "s", slicename,
+ "After", "as", 1, "libvirtd.service",
+ "Before", "as", 1, "libvirt-guests.service") < 0)
This makes domain a special kind of unit (scope) and sets its ordering dependency.
You can't do this with libvirtd.service itself because its different unit.
