Ludovic Courtès 2018-11-18linux-initrd: Return file-like objects instead of monadic values....This is an incompatible change visible to users via the 'initrd' field of 'operating-system'. However, assuming the user's 'initrd' value tail-calls to 'raw-initrd' or 'base-initrd', the switch to non-monadic style is invisible. * gnu/system/linux-initrd.scm (expression->initrd): Use 'computed-file' instead of 'gexp->derivation'. (raw-initrd, base-initrd): Adjust docstring to mention non-monadic return. * gnu/system/vm.scm (expression->derivation-in-linux-vm): Adjust accordingly. * gnu/system.scm (operating-system-directory-base-entries) (operating-system-initrd-file) (operating-system-boot-parameters): Adjust accordingly. * doc/guix.texi (operating-system Reference) (Initial RAM Disk): Update.

Remove 'if params' since dominating code assumed PARAMS is always true. (operating-system-boot-parameters): Remove 'system.drv' parameter; add #:system-kernel-arguments? instead and honor it. (operating-system-bootcfg): Adjust accordingly. (operating-system-boot-parameters-file): Likewise. * gnu/system/vm.scm (system-qemu-image/shared-store-script): Remove 'os-drv' variable. Adjust call to 'operating-system-kernel-arguments'. Ludovic Courtès 2018-11-18bootloader: De-monadify configuration file generators....* 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.

Ludovic Courtès 2018-06-20services: boot: Take gexps instead of monadic gexps....* gnu/services.scm (compute-boot-script): Rename 'mexps' to 'gexps' and remove 'mlet' form. (boot-service-type): Update comment. (cleanup-gexp): Remove 'with-monad' and 'return'. (activation-script): Rewrite in non-monadic style: use 'scheme-file' instead of 'gexp->file'. (gexps->activation-gexp): Remove 'mlet', return a gexp. * gnu/services/shepherd.scm (shepherd-boot-gexp): Remove 'with-monad' and 'return'. * gnu/system.scm (operating-system-boot-script): Remove outdated comment. * gnu/tests/base.scm (%cleanup-os): For 'dirty-service', remove 'with-monad' and 'return'.

Leo Famulari 2018-03-07services: file-systems: Include 'user-file-systems' service....Previously the KNOWN-FS value used in 'essential-services' would be incomplete: it would lack all the file systems provided by services that extend 'file-system-service-type' (/sys/fs/cgroup, /proc/sys/fs/binfmt_misc, etc.) Consequently, upon shutdown, 'user-processes' would unmount these file systems before their corresponding service had been stopped; when their corresponding (e.g., 'file-system-/proc/sys/fs/binfmt_misc') was stopped, its 'umount' call would fail. This was harmless in practice, but this patch makes sure things work as intended and file systems are unmounted in the right order. * gnu/services/base.scm (file-system-shepherd-services): Instantiate 'user-file-systems' Shepherd service from here. (user-unmount-service-type, user-unmount-service): Remove. * gnu/system.scm (essential-services): Remove call to 'user-unmount-service'. * gnu/system/install.scm (cow-store-service-type): Adjust comment.
