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 Derrick Ornelas 2022-04-15 00:04:32 UTC 
Description of problem:  Some of the data, specifically /etc/os-release, collected when running sos report on a RHCOS node via toolbox is from the support-tools container and not the host.  


Version-Release number of selected component (if applicable):
sos-4.1-9.el8_5
toolbox-0.0.8-4.rhaos4.10.el8
rhel8/support-tools:8.5-18 container image


How reproducible:  100%


Steps to Reproduce:
1.  Run toolbox on RHCOS 410.84.202202251620-0 node
2.  Run sos report in the toolbox container


Actual results:

The collected contents of /etc/os-release will be from the support-tools container

So, sos follows the symlink and gets os-release contents from the container.  There may be other files where the same thing is happening, but I haven't fully explored that yet.
Comment 1 Pavel Moravec 2022-05-08 15:44:21 UTC 
I do feel we have fixed such sort of an issue but I cant find when; could you please try it with sos-4.2 or sos-4.3 or current upstream (e.g. from https://github.com/sosreport/sos/releases)?
Comment 2 Derrick Ornelas 2022-05-26 00:11:44 UTC 
This doesn't appear to be fixed in 4.2 or 4.3
