11:04 < mvdan> we should update libre/grub-legacy, it tries to uninstall the new libre/grub package
11:04 < mvdan> :: Replace grub with libre/grub-legacy? [Y/n]
11:04 < mvdan> (that's a normal pacman -Syu)
[...]
13:32 < GuestOne> hey, with the new grub grub-mkconfig -o /boot/grub/grub.cfg  doesn't work anymore
[...]
13:38 < fauno> is grub-legacy replacing grub-bios?
13:38 < GuestOne> yes
13:38 < fauno> it shouldn't

Arch solves this by not having grub-legacy, we could do the same or update it to not replace grub.
