Eq. you want to generate an image that will boot on both BIO or UEFI system, with Anaconda. I think that makes perfect sense for (cloud) images, to make them boot anywhere. > > Yet for an installation to physical hardware, I don't think it makes sense - it's either configured to boot as a BIOS machine or an UEFI machine, so making the thing both BIOS + UEFI capable IMHO does not make sense. Having both options in place would just complicate things, consume extra space & make it more fragile. > > Ho do you invoke Anaconda in this case ? With --image or something like that ? Maybe that could be wired to make the resulting image hybrid, but not trigger on installations to physical or virtual hardware ? > Anaconda is invoked with either Lorax or ImageFactory+Oz for producing these images. But if it's a kickstart flag, I can also extend appliance-tools to handle it too. -- 真実はいつも一つ！/ Always, there's only one truth! _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@xxxxxxxxxx https://listman.redhat.com/mailman/listinfo/anaconda-devel-list
