Description of problem:
In the settings of KDM (KDE -> Systemsettings > LoginScreen > Shutdown > "Boot Manager"), the drop-down list should select by default "GRUB2" (instead of "NONE") since Fedora is shipped with GRUB2.
Version-Release number of selected component (if applicable):
Fedora 18, fresh installation (KDE 4.9.5)
Boot Manager = None (default value)
Boot Manager = Grub2
This option is important for the integration of Grub2 into KDM, which doesn't work by default (after a fresh Fedora installation).
[i.e. KDM is able to be aware of the different kernels to which it can reboot from]
[Remark: there is no "KDM" component in the list of products ?]
No can do, sorry, selinux-policy maintainers won't allow it.
(And KDM is in kde-workspace, but this is about Fedora default settings, so kde-settings is the right component.)
OK, but what is the reason ? Can you provide an explanation ?
Does this mean that Grub2 integration in KDM is not possible (by default) in Fedora ? Yet it was presented as a Fedora 16 feature ! (see https://fedoraproject.org/wiki/Releases/16/FeatureList -> https://fedoraproject.org/wiki/Features/KDE47 )
> OK, but what is the reason ? Can you provide an explanation ?
They think that allowing the login manager to change bootloader configuration is inherently dangerous.

Yes, as long as SELinux is enabled by default (and I see no plans to change this, even though I'd support that) and as the SELinux maintainers keep their position, we cannot enable GRUB integration by default.

The feature is that the option exists and can be enabled if you disable (or customize) SELinux at the same time. What's new in Fedora 16 is that it uses GRUB 2 instead of GRUB 1, which is why GRUB 2 support is mentioned in the KDE47 feature page at all.
