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:
rd_NO_LUKS rd_NO_LVM rd_NO_MD rd_NO_DM is specified in cmdline, and no have any RAID or LVM, but, rc.sysinit, check the /proc/devices, and see device-mapper and load dm_mod module.
I no have any device-mapper, no use any RAID, LVM or encription for / or /home.
So, dm_mod is loaded for a error in device mapper or kernel, that report an no present device in /proc/devices.
I mofidy the /etc/dracut.conf uncommented the line hostonly, and adding the module for not load, and recreated the initrd image, but, the module is loaded anyway.
Fedora 13, rd_NO_DM rd_NO_MD work, and prevent the load of modules at start
dracut.conf
cat /etc/dracut.conf
