Alrighty, just make sure it is very clearly and prominently stated
in the release notes.

Nope. As you well know, in Devuan I'll only deal with things
related to the mirror network right now, thank you.

Yes, it can be FUD and I can be wrong and biased.
That's because these were literally the first two things that came
to mind in a thought exercise of 5 minutes, and they both had the
potential to be problematic after checking a bit; I just confirmed
they are problematic in practise.

The case of Ansible: it relies ansible_distribution and
ansible_distribution_release being properly defined (and they come
from lsb_release).
This is used, e.g. to provision servers and machines and, amongst
other things, to decide which repositories are to be enabled in
certain machines.
If the system says it's Debian, it's not crazy to set it up with
the repositories in the closest **Debian** mirror; that's a fun
state for Devuan to find itself in.
Other provisioning tools do similar things by default (make
decisions based on "constants/facts" provided by the system).

The case of unattended-upgrades: indeed as predicted it now
installs Debian's /etc/apt/apt.conf.d/50unattended-upgrades, which
means that it won't match Devuan's repositories.
So, the patch that we landed upstream months ago is effectively
being ignored. If the package isn't forked, people's expectation
that unattended-upgrades will install security upgrades by default
will be broken.

Maybe I was super lucky and these are the only two issues, maybe
not.

In the end everything can be worked around by good sysadmins
though, that's why it's important that this is listed in the
release notes both clearly and prominently.
