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 Hans de Goede 2010-05-28 10:36:25 UTC 
When a usb stick is plugged in during installation, it now often becomes sda
(since the usb mass storage scanning delay was reduced). This results in a means /boot/grub/device.map getting writting which contains:
(hd0) /dev/sdb

If the user then later needs to re-install grub and uses the device.amp, without the usb stick present. Things go wrong.

As /dev/sdx names are not really stable it would be much better to write
/dev/disk/by-path/... paths to device.map .
Comment 2 Peter Jones 2010-08-20 21:08:21 UTC 
/dev/disk/by-path/ for that is a really bad idea - disk paths change sometimes when new pci devices are installed due to pci enumeration weirdness.
