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 Corey Marthaler 2017-12-20 19:01:05 UTC 
Description of problem:

I assume more of the options below should have been filed in with this creation attempt?

[root@mckinley-03 ~]# boom profile create --from-host 
Created profile with os_id e681b91:
  OS ID: "e681b91cc8ac8061fad519e6588ec842c728697a",
  Name: "Red Hat Enterprise Linux Server", Short name: "rhel",
  Version: "7.4 (Maipo)", Version ID: "7.4",
  Kernel pattern: "/vmlinuz-%{version}", Initramfs pattern: "/initramfs-%{version}.img",
  Root options (LVM2): "rd.lvm.lv=%{lvm_root_lv}",
  Root options (BTRFS): "rootflags=%{btrfs_subvolume}",
  Options: "root=%{root_device} ro %{root_opts}"

Which lead to the following list failures:

Comment 2 Bryn M. Reeves 2018-01-08 17:30:09 UTC 
This is the same basic problem as bug 1528014 (not including the built-in profiles), but with an added bug in the exception handler: the OS identifier is undefined when we attempt to print it in this case (the code was written to also output the file name but the format tuple is incorrect).

I'll change this to only print the name of the file that could not be read.
Comment 4 Corey Marthaler 2018-01-30 18:52:24 UTC 
Marking verified in the latest rpms. Boom profiles can now be created and properly used.
