That sounds like it is true. However, it also seems to imply that<br>
dh_installsystemd and dh_installinit must forever be tangled some how.<br>
If true, that is very much unfortunate as it makes the interaction a lot<br>
more complicated than it should be (case in point, this bug is caused<br>
exactly by these two commands being tangled).<br>
<br>
Do you see a solution for this, where dh_installsystemd and<br>
dh_installinit can become independent/unaware of each other?<br>
Alternatively, should we merge them into a single helper instead?<br></blockquote><div><br></div><div>I think the entanglement can be removed by runtime checking of the unit.</div><div><br></div><div>1.
