Consider placing this into the **Packaging changes**, don't think this
is tha much interesting to end users.

Hmm, you're probably right. The thing is though that these changes were
done because distros (fedora in this case) did some shenanigans with
moving /sbin/ into /bin/ but differently based on if you upgraded or
installed freshly, which actually broke some stuff for users as paths
were compiled in.

That fact isn't obvious from what I wrote if you don't know the
backstory.

Any suggestions?
