Hello Artur Molchanov,

Thanks for your bug report.

You seem to be confused about the cause. This is simply a bug in the
ipmiutil packaging and doesn't really have anything special to do
with invoke-rc.d/init-system-helpers.

For the record here's the output of trying to install ipmiutil on
Debian Stretch:

Errors were encountered while processing:
 ipmiutil
E: Sub-process /usr/bin/dpkg returned an error code (1)

The service is first enabled and then (attempt to get) started
because that's what the packages maintainer script says should
happen. If the maintainer didn't want something to be enabled/started
he would pass the --no-enable or --no-start arguments respectively.
This is not done...

The real reason the start fails (and thus the package configuration
and thus installation fails) is because the executed process
exits with a failure code. It seems atleast on my system the
reason for that is that my system simply isn't IPMI capable.

Also the service files shipped by the debian package seems to have
fundamental flaws. These files are declarative format and *not*
shell scripts! (if you want to run shell script stuff, just invoke
/bin/sh -c '....' from your service file, or put the commands
in an actuall shell script file and execute the shell script.)

ah at mbpah:/tmp/ipmiutil-3.0.0$ grep ExecStart debian/*ipmi_port.service
ExecStart=/usr/share/ipmiutil/ipmiutil.setup >/dev/null && /usr/sbin/ipmi_port -b || : 

(Preferably service files should come directly from upstream
rather than being debian-specific.)

As there seems to multiple serious packaging issues here I'm raising
the severity accordingly.

Thanks for the cross-reference. You might want to add a link to
this bug report on the ubuntu side.
