Dear maintainer(s),

With a recent upload of dnsmasq the autopkgtest of systemd fails in
testing when that autopkgtest is run with the binary packages of dnsmasq
from unstable. It passes when run with only packages from testing. In
tabular form:

                       pass            fail
dnsmasq                from testing    2.86-1
systemd                from testing    247.9-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of dnsmasq to
testing [1]. Due to the nature of this issue, I filed this bug report
against both packages. Can you please investigate the situation and
reassign the bug to the right package?

[0] You can see what packages were added from the second line of the log
file quoted below. The migration software adds source package from
unstable to the list if they are needed to install packages from
dnsmasq/2.86-1. I.e. due to versioned dependencies or breaks/conflicts.
