Doc Type: Known Issue
Doc Text:
If Fedora 17 or later is installed on the system, the kernel uses a shared /boot partition, and the user installs Red Hat Enterprise Linux 7.0 Beta which uses the same /boot partition, the latest kernel will be used by GRUB 2. That is, Red Hat Enterprise Linux 7.0 Beta can use a Fedora kernel if this is later, resulting in certain modules to be limited or non-functioning (for example, sound or networking). To work around the problem, the correct kernel must be chosen manually.

Description Vladimir Benes 2012-05-22 11:44:53 EDT
Description of problem:
when installing rhel7 over f17 and using same boot partition (this seems to be quite common) grub mkconfig choses f17's kernel as default option as it's newer. Then I need to go into advanced option and chose the rhel7 one.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.install F17 or any newer kernel into shared partition 
2.install RHEL7 with option to install grub enabled
3.boot RHEL7 default option
Actual results:
wrong plymouth
modules (e.g networking) unavailable
need to go into advance options and chose correct kernel there

Expected results:
correct kernel chosen as default option

just to explain more: I installed RHEL7 next to F17 no update.. clean install.. no update

Could you verify that bug is still valid for RHEL 7.0 Alpha 2?

yes, it does!
Comment 5 David Cantrell 2013-10-28 11:44:50 EDT
This is entirely valid, but is the nature of things when dealing with Fedora and RHEL on the same system.  Fedora will almost always have a more recent kernel than RHEL.

I'm moving this out to 'rc' for the target because I don't feel it's really critical for beta.
