Skip the 35 comments. The first two lines of the description contain the entire point. All that needs to happen for bootloader=no is insert '--grub-setup=/bin/true' as an option for grub2-install. It's actually simplifying the code path than what we currently have because everything else stays exactly the same as when bootloader=yes; and --grub-setup=/bin/true is the upstream recommended practice for this use case. So it's already well tested.
It really can be fixed for Fedora 21. We know what fix is needed, and it's safe. So someone who cares about this, who knows a bit of python, should put together a patch per this:
http://fedoraproject.org/wiki/Anaconda/ReviewProcess
And then also propose that bug for Fedora 21 beta freeze exception. It's virtually certain it'd pass. I mean, it probably could be incorporated without a freeze exception if it goes in before beta freeze (?) but then at least it's on a list and has some extra attention. It's a 2 year old bug, let's squash it.
Maybe this discussion should be moved over to the anaconda-devel-list.
Anyway, now that you have a tested way to get grub2 installed and
configured but *not* in the MBR, it is just a SMOP to implement [SMPO =>
Small Matter Of Programming:-) ]
I think it is a bit more than that ... how do we *specify* that we do
not what the MBR updated. The simplest way I could think of is to use
an anaconda boot option similar to using "extlinux" for anaconda to
install extlinux rather than grub2. Maybe "nombr" or "nombrupdate"?
This would be a simple way to specify it and have things work for
kickstart and non-kickstart installs.
Comments?
