system: grub: Allow arbitrary kernel file names in 'menu-entry'.
Fixes <http://bugs.gnu.org/20067>. Reported by Tomáš Čech <sleep_walker@suse.cz>. * gnu/system.scm (system-linux-image-file-name) (operating-system-kernel-file): New procedures. (operating-system-grub.cfg): Use 'operating-system-kernel-file' for the 'kernel' field of 'menu-entry'. (operating-system-parameters-file): Likewise for the 'kernel' entry. (read-boot-parameters): Adjust 'kernel' field so that it contains the absolute file name of the image. * gnu/system/grub.scm (grub-configuration-file)[linux-image-name]: Remove. [entry->gexp]: Assume LINUX is the absolute file name of the kernel image. * doc/guix.texi (GRUB Configuration): Add an example, and adjust 'kernel' field documentation accordingly.
