Ok, but assuming that is the fix (install systemd-sysv or systemd-shim), how
did bug #7533357 happen?  Notwithstanding Juliusz's desire to not have
systemd installed (which I don't expect us to address), if both of those
packages were missing from the system, then something is buggy.  Juliusz,
can you please paste your apt logs showing what pulled systemd in on the
system?

If something is depending on systemd directly without either systemd-sysv or
systemd-shim, that something is buggy.

If systemd-sysv *was* installed and logind wasn't working, this probably
points to the bug with logind being broken before reboot to systemd.

However, acpi-support-base also needs to make sure that logind is functional
before delegating control of the power button to it.  And for that, I see
that acpi-support 0.141-4 introduced a change in unstable *yesterday* to
deal with exactly this problem: instead of only checking for a running
logind, acpi-support-base now checks the systemd dbus interface to verify
that logind is running and usable.  So it's possible that Juliusz's issue is
a duplicate of bug #752781.

It should not be the user's responsibility to install this package manually
to get back to a working system.

Well, I think the behavior of acpi-support-base is *now* correct in
unstable, in response to bug #752781.  I don't think it's correct in
testing.
