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:
%post scriptlet of spice-streaming-agent executes restorecon and semanage:
[root@localhost ~]# rpm -q --scripts spice-streaming-agent
postinstall scriptlet (using /bin/sh):
semanage fcontext -a -t xserver_exec_t /usr/bin/spice-streaming-agent 2>/dev/null || :
restorecon /usr/bin/spice-streaming-agent || :
...
But restorecon and semanage don't work if selinux-policy-* is not yet installed (for example during the installation of a system, see bug 1367433 for details). It was recommended to execute the commands in %posttrans to avoid possible issues with the SELinux policy being installed later in the transaction.
Bug 1367433 comment 14: "You should also hide the stderr output of restorecon for when the package is installed on a system with disabled selinux (or inside a container). In such case the command is expected to fail (and the message is therefore harmless)."
Version-Release number of selected component (if applicable):
RHEL-7.6
spice-streaming-agent-0.2-3.el7
How reproducible:
always
Steps to Reproduce:
1. check rpm scriptlets
Actual results:
restorecon and semanage are executed in %post
Expected results:
restorecon and semanage are executed in %posttrans, stderr is redirected to /dev/null
I still see the issue in nightlies (RHEL-7.7-20190415.n.1), maybe there is some action needed to have the fix in compose?

10:44:19,990 INFO packaging: No such file or directory
Ok, the issue is gone. I no longer see it there during the installation (RHEL-7.7-20190416.n.0):
