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:
The uuidd.socket file requires that /var/uuidd/ exist, but the uuidd package doesn't own that directory nor create it during installation. This creates problems with a readonly root file system. Further, /var/uuidd/request should probably be added to /etc/rwtab.d
It does however provide /run/uuidd/ which is where the service file should be pointing to in the first place and the issue with the service file is corrected upstream in git:
https://git.kernel.org/pub/scm/utils/util-linux/util-linux.git/commit/misc-utils/uuidd.socket.in?id=8df545592d73b67b0bf119732b52a5e4c0662ec4
Version-Release number of selected component (if applicable):
uuidd-2.23.2-61.el7.x86_64
Good catch.
It really seems util-linux spec file assume /run/uuidd
%dir %attr(2775, uuidd, uuidd) /run/uuidd
but uuidd.h code
#define UUIDD_DIR _PATH_LOCALSTATEDIR "/uuidd"
#define UUIDD_SOCKET_PATH UUIDD_DIR "/request"
and /usr/lib/systemd/system/uuidd.socket
[Socket]
ListenStream=/var/uuidd/request
still use the original /var/uuidd/.
It would be probably better (less risky for RHEL-7.x update) fix the spec file rather than touch the code. Note that people around SAP are extremely sensitive to arbitrary uuidd change, so I'd like to avoid any path change in code and package build system. The spec file chnage is trivial without any side-effect.
(RHEL-8 uses everywhere the same path to /run/uuidd.)
