The Fedora 23 final release criteria includes criteria for Windows and OS X but not Linux. The last time this was brought up was Fedora 21. Exiting *dual boot* (not multiboot) language: Windows dual boot The installer must be able to install into free space alongside an existing clean Windows installation and install a bootloader which can boot into both Windows and Fedora. OS X dual boot The installer must be able to install into free space alongside an existing OS X installation, install and configure a bootloader that will boot Fedora. Suggested Linux dual boot language The installer must be able to install into free space, including free space created by an installer supported shrink operation, alongside an existing Linux installation and configure a bootloader that will boot both Linux OS's. So that suggests if the installer supports shrink of ext3/4 (which it does) this should work; if it's free space (no shrink) it should work, it doesn't obligate the installer to support Btrfs shrink even though btrfs shrink is stable, but it does obligate the installer to make LV's active so that os-prober can locate any possible Linux installations. And it only holds the installer and by extention os-prober and grub2-mkconfig to creating boot entries for two Linux OS's. If it finds 25+ OS installations and pukes, that's not covered by this. So I don't know what all edge cases could exist and if there needs to be a fail safe? i.e. if there are more than x number inactive LVs (not created by this installation session) that would need to be made active so that os-prober can search for other OS's, then just fail? I'm not suggesting the critieria should obligate the installer team to create a fail safe, but rather to suggest somehow that if there's some weird edge case with piles of LVs that need to be activated and searched (possibly none of which even have a Linux OS on them), that this criterion doesn't apply at al. I've thrown out 25, but there's no empirical method involved in picking that. And yes this ultimately needs to go on anaconda@ and maybe desktop@ but I wanted to vet this with testers first and get the language more sane and concise.
