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 Petr Pisar 2020-06-10 15:48:30 UTC 
After upgrading systemd-udev from 239-30.el8_2 to 239-33.el8, installing kernel-core package produces a scriptlet warning:

The reason is that "udevadm --version" changed format from:

# udevadm --version
239

to:

# udevadm --version
239 (239-33.el8)

/usr/lib/dracut/dracut-init.sh from dracut-049-86.git20200602.el8.x86_64 parses "udevadm --version" output:

   446  prepare_udev_rules() {
→  447      [ -z "$UDEVVERSION" ] && export UDEVVERSION=$(udevadm --version)
   448  
   449      for f in "$@"; do
   450          f="${initdir}/etc/udev/rules.d/$f"
   451          [ -e "$f" ] || continue
   452          while read line || [ -n "$line" ]; do
   453              if [ "${line%%IMPORT PATH_ID}" != "$line" ]; then
   454                  if [ $UDEVVERSION -ge 174 ]; then
   455                      printf '%sIMPORT{builtin}="path_id"\n' "${line%%IMPORT PATH_ID}"
   456                  else
   457                      printf '%sIMPORT{program}="path_id %%p"\n' "${line%%IMPORT PATH_ID}"
   458                  fi
   459              elif [ "${line%%IMPORT BLKID}" != "$line" ]; then
→  460                  if [ $UDEVVERSION -ge 176 ]; then
   461                      printf '%sIMPORT{builtin}="blkid"\n' "${line%%IMPORT BLKID}"
   462                  else
   463                      printf '%sIMPORT{program}="/sbin/blkid -o udev -p $tempnode"\n' "${line%%IMPORT BLKID}"

   467              fi
   468          done < "${f}" > "${f}.new"
   469          mv "${f}.new" "$f"
   470      done

Either systemd-udev should revert the format, or dracut should adapt.
Comment 1 Lenny Szubowicz 2020-06-11 01:12:53 UTC 
I just ran into this as well. FWIW, I think dracut should adapt to the change. Seems risky to depend on a version string being a simple integer value.

Perhaps something like this would work:
