WARNING: dh_installsystemd is moving unit files to /usr/lib/systemd/system

["Theodore Ts'o" <tytso@mit.edu>]

There appears to be a rather major regression in debhelper 1.13.4 and
1.13.4nmu1, which is forcing unit files to go in
/usr/lib/systemd/system, instead of /lib/systemd/systemd (where sytemd
will actually pay attention to them).

On systems with ursmerge, things should still work, thanks to the
compatibility symlink, but this will cause packages with unit files
built since debhelper 1.13.4 was released to unstable, or uploaded as
source builds, to be incorrect, triggering a Lintian error and
breaking on systems that don't have usrmerge installed.

For more details and analysis, please see:

I just wanted to post a warning that if you were planning on building
or uploading new source-only uploads to unstable now that Bullseye has
been released, and your package contains systemd unit files, you may
want to hold off until this bug gets fixed...
