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 Tereza Cerna 2015-10-05 12:26:05 UTC
File /etc/default/grub contain row with variable GRUB_CMDLINE_LINUX_DEFAULT if tuned is installed. If package tuned is uninstall, this row should not be in /etc/default/grub.

There is nonactual regex in %postun.

# rpm -q tuned
tuned-2.5.1-4.el7.noarch

# cat /etc/default/grub | grep GRUB_CMDLINE_LINUX_DEFAULT=
GRUB_CMDLINE_LINUX_DEFAULT="${GRUB_CMDLINE_LINUX_DEFAULT:+$GRUB_CMDLINE_LINUX_DEFAULT }\$tuned_params"

# yum remove tuned 
# rpm -q tuned
balíček tuned není nainstalován

# cat /etc/default/grub | grep GRUB_CMDLINE_LINUX_DEFAULT=
GRUB_CMDLINE_LINUX_DEFAULT="${GRUB_CMDLINE_LINUX_DEFAULT:+$GRUB_CMDLINE_LINUX_DEFAULT }\$tuned_params"

Row GRUB_CMDLINE_LINUX_DEFAULT=... should be removed during uninstall.

Comment 2 Jaroslav Škarvada 2015-10-06 12:24:01 UTC
The tuned footprint in /etc/default/grub was improved to deal with whitespaces, but the clean-up regex in SPEC wasn't updated.
