Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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 of problem:
systemctl preset-all disables but wont enable default.target.
So if the target is not enabled in preset policy it is removed. If it is enabled in default policy however it is not added. This is confusing behaviour.
It should either work for both or none.
Version-Release number of selected component (if applicable):
systemd-219-19.el7_2.4.x86_64
How reproducible:
Everytime
Steps to Reproduce:
1. # No reference to multi-user.target in any systemd-preset files (ie uses 99-default.preset)
2. sudo systemctl preset-all
3. # Add "enable multi-user.target" to a systemd-preset file (eg /etc/systemd/system-preset/01-target.preset)
4. sudo systemctl preset-all
Actual results:
$ sudo systemctl status multi-user.target

Additional info:
Possibly if it works for both a default preset policy should be added to:
/usr/lib/systemd/system-preset/90-default.preset
Ok, so this actually works as it should. See the uspstream issue for details.
To sum up:
The 'preset-all' command removes default.target, even if it's in the configuration file, because "default.target" is not an actual name of a unit file. Also, when "multi-user.target" or "graphical.target" is specified in the configuration, it is not enabled as it doesn't have an Install section (see https://github.com/systemd/systemd/commit/02ebe178a2bd6b2448d4fbfa4a1f7fa98e9e82b1 for the reasoning).
