RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Renaud Métrich 2022-03-18 09:38:35 UTC 
Description of problem:

Since 2016, tuned.service has a Requires dependency on polkit.service:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
Requires=dbus.service polkit.service
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

IMHO this dependency is overkill and brings trouble.
Indeed, with such dependency, as soon as polkit gets restarted (e.g. due to having a "systemctl try-restart polkit.service" in RPM snippets), this leads to tuned.service being restarted as well.

IMHO the following dependency is enough:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
After=polkit.service
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

Quick testing shows that with the above dependency only, tuned works fine at boot.
Also upon stopping polkit service and issuing a "tuned-adm active" command, the polkit service is started automatically and the command works just fine.


Version-Release number of selected component (if applicable):

tuned-2.16.0-1.el8.noarch


How reproducible:

Always

Steps to Reproduce:
1. Stop polkit.service

  # systemctl stop polkit

Actual results:

tuned.service also stops

Expected results:

tuned.service continues normally

Additional info:

Makes any "tuned-adm" command unavailable.
Comment 1 Jaroslav Škarvada 2022-10-11 10:20:58 UTC 
I think you are right, polkit has D-bus activation, thus we don't need to explictly require it.
