move systemd bits from 56-hpmud_sysfs.rules to 56-hpmud.rules

[Jiri Popelka]

Prior to 3.15.6 both 56-hpmud_sysfs.rules & 56-hpmud.rules contained
if [ -f /usr/bin/systemctl ]; then /usr/bin/systemctl --no-block start hplip-printer@$env{BUSNUM}:$env{DEVNUM}.service

With 3.15.6 this has been removed from 56-hpmud.rules, but still remains in 56-hpmud_sysfs.rules.
AFAICT 56-hpmud_sysfs.rules, which uses deprecated SYSFS instread of ATTR, exists only for older distributions like RHEL5, where there's no systemd. So IMHO it should have been removed from 56-hpmud_sysfs.rules, not from 56-hpmud.rules.

You might also consider using "TAG+="systemd", ENV{SYSTEMD_WANTS}=..." instread of RUN+=""

Hello Jiri,

systemctl syntax was intentionally removed from 56-hpmud.rules, because RUN+= syntax is good enough to execute "hp-config_usb_printer" script(It does not take more time to run and does not create any daemon) . Regarding 56-hpmud-sysfs.rules, we should have removed systemctl syntax from this file as well but somehow missed it. Please let me know if you see any issues in 56-hpmud.rules.

Seb, this is still an upstream issue as it is reported by a Red Hat developer and worked on by the upstream developers at HP. So do not replace the upstream task by a task for the Ubuntu package, but if you want to make me as the Ubuntu maintainer of HPLIP aware of the bug, simply add the Ubuntu package task.

Re-added upstream task.

Seb, did you perceive any breaking effect by this in Wily? Is the problem release-critical? Or can we simply wait for the upstream developers to fix it (and then have the fix in 16.04)?

Hello Jiri,
Thank you for submitting this bug and reporting a problem with hplip. You made this bug report some time ago and Ubuntu and hplip have been updated since then.

Could you confirm that this is no longer a problem and that we can close the ticket?
If it is still a problem, are you still interested in finding a solution to this bug?
If you are, could you let us know and, in the current version, could you run the following (only once):
apport-collect 1479431
and upload the updated logs and and any other logs that are relevant for this particular issue.

Thank you again for helping make Ubuntu and hplip better.
