After installing grub2 there is message shown: " * - For grub2 just run grub-mkconfig, a configuration file is installed * as /etc/grub/39_memtest86+ " There is no such path as "/etc/grub/39_memtest86+" It should be "/etc/grub.d/39_memtest86+"
File is installed properly: $ qlist memtest86+ /etc/grub.d/39_memtest86+ Only elog message is wrong. Fixed in 4.20-r{1,2},5.01 without revision bump.
