* gnu/bootloader/extlinux.scm: Remove unneeded imports. (extlinux-configuration-file): Use 'computed-file' instead of 'gexp->derivation'. * gnu/bootloader/grub.scm (svg->png): Likewise. (grub-background-image, eye-candy): Adjust accordingly, return non-monadically. (grub-configuration-file): Likewise, and use 'computed-file' instead of 'gexp->derivation'. * gnu/bootloader/u-boot.scm: Remove unneeded imports. * gnu/system.scm: Add 'lower-object' call.
