Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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 Xunlei Pang 2017-03-29 10:36:15 UTC 
Description of problem:
We currently pass "--hostonly-cmdline" to dracut when making kdump initramfs,
this is useful to collect more information on the host, but on the other hand it also results in more needless stuff added to kdump.

For example, more host devices(like lvm devices, devices mounted to /boot, /boot/efi, etc) will be generated as "wait_for_dev", then kdump must wait for all the devices ready.

Actually, Fedora doesn't have "--hostonly-cmdline", it works all the time as well. There is some difference regarding dracut between RHEL7 and Fedora, we need to investigate and see if can keep align with Fedora.

After some discussion within team, we decided to keep "--hostonly-cmdline" and add the new "--no-hostonly-default-device" feature instead.
