I asked a while ago on grub-devel@ whether grub-mkconfig depended on grub-install being done first, and I got a kinda yesish answer that wasn't all that convincing. But the suggestion was to use 'grub2-install --grub-setup=/bin/true /dev/sdX' before grub2-mkconfig. This causes all the parts of grub to be installed except the singular thing people object to, and is the sole reason why they say they don't want a bootloader installed - which is boot.img being written into the MBR. > > I've tested that combination and it's safe. So if the code were changed just that "no bootloader" simply means *adding* --grub-setup=/bin/true and doing everything else we already do, that'd be the easiest fix that helps the most people IMO. > > BTW I think device.map is deprecated (?). I dunno, it's in there for the regular grub2 install so I kept it for the 'non-install-install' I'm suggesting. bootloader.py is really falling-off-a-log-simple code, it wouldn't be at all difficult to implement just about any approach to this, AFAICS. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/anaconda-devel-list
