I'm installing RHEL6 Beta2 to a disk which already has LVM configured and RHEL5.
sda1 - 200MB boot
sda2 - ~160GB LVM
* lv_root_1 (ext3, has RHEL5)
* lv_root_2 (ext4, trying to install RHEL6 here)
* lv_root_3 ...
* lv_root_4 ...
I want to make sure that when I install grub to sda1 I don't lose my RHEL5 entries, which Boot loader operating system list seems to suggest.
So I added an entry "Red Hat Enterprise Linux 5", but when I hit 'edit' it doesn't allow me to select device different from 'sda1'. RHEL6 is correctly setup for vg_root_kovy-lv_root_2.
This is not very user friendly, since I'm left with 2 bad choices:
* do not install grub. After RHEL6 install boot RHEL5 and add the entries manually.
* install grub. Boot RHEL6 and add RHEL5 entries back.

This request was evaluated by Red Hat Product Management for inclusion in a Red

review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release. This request is not yet committed for
The "Boot loader operating system list" is not there for automatic merging of (grub) boot configurations (we don't support it) but for chain-loading, that is, for your case you'd need to keep old RHEL5 boot partition, have bootloader installed in it, and for RHEL6 create a new boot partition from which grub would chain-load the RHEL5 boot partition bootloader. I am closing this as NOTABUG, you can open RFE for the requested feature. We have already one similar bug #568542 for Fedora.
Alright, reopening this then as an RFE
Adding another system in bootloader configuration doesn't work
Support for merging grub configuration files of older RHEL releases
This feature request did not get resolved in time for Feature Freeze
for the current Red Hat Enterprise Linux release and has now been
denied. You may re-open your request by requesting your support
representative to propose it for the next release.
Merging an existing /boot with a new /boot is not supported in anaconda. This is a very tricky area to get in to and would introduce many problems if people have other Linux distributions installed. It is not a use case we want to support in anaconda.
