I would have thought all modern boot loaders can read ext* filesystems, without needing to specify the filesystem type by passing the kernel parameters yourself to the boot loader. However, I don't use genkernel to know how to configure/modify it so it boots with different boot managers. If the details are not explained in the links I provided above, someone experienced in using genkernel should give some pointers. signature.asc Description: This is a digitally signed message part.

If it is not built in-the-kernel, but as a module, then it should be in initramfs.

Re: [gentoo-user] system won't boot - --no-bootloader set; Skipping bootloader update ...
you didn't specify grub2 on the command line or (my preference) in /etc/genkernel.conf. So genkernel assumes you don't want it to fix your boot loader. If the kernel and ramdisk are all built, you can fix grub's config with grub-mkconfig -o /boot/grub/grub.cfg. For future kernel builds, read the paramaters in man genkernel so you know how to specify the boot loader, or just edit /etc/genkernel.conf and set the bootloader from none to grub2.
