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:
Systemd fails to mount namespace when using RootDirectory=some_ath, DynamicUser=true and StateDirectory, LogsDirectory etc.
This issue was already reported to systemd upstream (https://github.com/systemd/systemd/issues/22264) and they made a patch to fix it (https://github.com/systemd/systemd/pull/22272), however it has not currently been backported to the systemd package used by RHEL 9.1.
Version-Release number of selected component (if applicable): 250-12.el9_1.1
Steps to Reproduce:
1. wget https://dl-cdn.alpinelinux.org/alpine/v3.17/releases/x86_64/alpine-minirootfs-3.17.2-x86_64.tar.gz -O /tmp/rootfs.tar.gz
2. mkdir /tmp/rootfs && tar xf /tmp/rootfs.tar.gz -C /tmp/rootfs
3. chcon -R -t bin_t /tmp/rootfs/bin
4. chcon -R -t lib_t /tmp/rootfs/lib
5. sudo systemctl daemon-reload
6. sudo systemctl start test
7. systemctl status test
Content of unit test.service:
[Service]
DynamicUser=true
StateDirectory=foo
RootDirectory=/tmp/rootfs
ExecStart=/bin/cat /etc/os-release

Additional info:
I was able to patch the systemd RPM package source used by RHEL and compile the systemd RPM package solving the issue, it would be helpful to update the RHEL 9 systemd package with the addition of the patch (https://github.com/systemd/systemd/pull/22272)
