Grub configuration interpretes `linux' as directory where is located
bzImage. If I enter file name instead, result configuration will be
wrong.


Example of system configuration:
(bootloader (grub-configuration
	      (device "/dev/sda")
	      (menu-entries
	       (list
		(menu-entry
		 (label "Gentoo")
		 (linux "/vmlinuz-gentoo") ; vmlinuz-gentoo is file
		 (linux-arguments (list
				   "root=/dev/venom/gentoo"
				   "init=/usr/lib/systemd/systemd"))
		 (initrd "/initramfs-gentoo")
		 )))))



Result part of grub.cfg:
menuentry "Gentoo" {
  # Set 'root' to the partition that contains the kernel.
  search --file --set /vmlinuz-gentoo/bzImage


  linux /vmlinuz-gentoo/bzImage root=/dev/venom/gentoo init=/usr/lib/systemd/systemd
  initrd /initramfs-gentoo
}



It would be nice if the the string would be simply copied into
grub.cfg, so I could use even `(hd0,msdos1)/vmlinuz'.
