Improve the Grub /boot setup procedure, to support people with more unusual grub setups where the default config file may not be suitable to pass into the grub shell, per bug #218599. Include a stock grub.conf for Gentoo users. Install the splashimage to /usr and copy to /boot later rather than direct to /boot.

(Portage version: 2.1.5.2)
