<pre>Hi both Michal,
Thank you for the quick responses! I think I will keep on using the tedious
PartOf= directive.
However, may I ask why ConsistsOf= is readonly? If I can use it in my
"my-apps.target", that would be great.

Because "ConsistsOf" doesn't exist in the way you think it does...<br>
<br>
Every relation between units (Wants, Before, PartOf) needs to have
an<br>
internal, reverse relation for accounting purpose<br>
<br>
That reverse relation is usually an internal detail, but it is handy
to expose<br>
it in "systemctl show" & co.<br>
<br>
So that's what you see, an internal property exposed for
ease-of-use. not an<br>
external, user configurable property</div><div text="#000000" bgcolor="#FFFFFF"><br>

<pre>FTR (not helpful for the original problem), there exists ConsistsOf= as
an inverse of PartOf= dependency. However, it's read only currently (or
strictly speaking, writable through the PartOf= endpoint).
