Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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:
When issuing a reboot, or halt the system kills the S01reboot process and never completes a reboot or shutdown.

Version-Release number of selected component (if applicable):
initscripts-9.03.38-1.el6_4.2.x86_64

How reproducible:
Reboot a nfsroot system, bind mounts for RW parts of the FS may or may not be required to reproduce.

Steps to Reproduce:
1. reboot
2.
3.

Actual results:
system hangs after trying to umount filesystems

Expected results:
system reboots or halts

Additional info:
The issue appears to be in /etc/init.d/functions in the __umount_loop() function.

This line appears to be the culprit that kills S01reboot:
fstab-decode /sbin/fuser -m $remaining 2>/dev/null  | sed -e "s/\b$$\b//" | xargs kill $sig >/dev/null

fstab-decode /sbin/fuser -m $remaining reports back two copies of the scripts PID and the sed command only removes the first. Changing the regex for sed to "s/\b$$\b//g" resolves the issue, but there may be other issues in the function that are resulting in this being a problem.

This check was introduced in 6.4, before that it killed the script even in the case there was one pid. But thnaks for the report and we will fix that.
