* gnu/services/base.scm (file-system-service): Add #:requirements
parameter and honor it.
(device-mapping-service): New procedure.
* gnu/system/linux-initrd.scm (base-initrd): Add comment.
* gnu/system/linux-initrd.scm (expression->initrd): Remove #:linux and
#:linux-modules parameters. Remove call to
'float-linux-module-directory'.
(base-initrd): Add call to 'float-linux-module-directory'. Use it in
#:linux-modules argument in the gexp. Remove #:linux and
#:linux-modules arguments to 'expression->initrd'.
* gnu/build/linux-initrd.scm (build-initrd): Remove
#:linux-module-directory parameter. Don't create 'modules'
sub-directory.

now moved above. Use 'build-initrd'.
* gnu/system/linux-initrd.scm (expression->initrd): Remove calls to
'imported-modules' and 'compiled-modules'. Use 'gexp->script' with
EXP. Add the result to TO-COPY. Make /init a symlink to that script,
and copy its closure into the "contents" directory. Add fake
/proc/self/exe symlink.
* gnu/build/linux-boot.scm (load-linux-module*): Add comment about mmap.
* gnu/system/vm.scm (system-qemu-image/shared-store-script): Add "-m
256". This turns out to be needed for initrds containing things like
e2fsck and several modules; with the default of 128 MiB, loading
libahci.ko may fail with -1.

hack. Pass #:references-graphs to 'gexp->derivation'.

file system.

* gnu/services/dmd.scm (dmd-configuration-file): Select
'canonicalize-device-spec'.
This fixes a circular dependency between (gnu system) and (gnu system
linux-initrd), where the latter could end up being compiled before
'file-system-type' was defined as a macro.
* gnu/system.scm (<file-system>, %fuse-control-file-system,
%binary-format-file-system): Move to...
* gnu/system/file-systems.scm: ... here. New file.

default. Call 'check-file-system' before mounting ROOT, when
VOLATILE-ROOT? is false.
(check-file-system): New procedure.
(mount-file-system): Honor 'check?' element in list; add
'check-file-system' call.
(boot-system): Remove #:root-fs-type and #:unionfs parameters.
[root-mount-point?, root-fs-type]: New variables.
Call 'mount-file-system' on all MOUNTS but "/".

'qemu-initrd'.
(<file-system>): New record type.
(operating-system-root-file-system): New procedure.
(operating-system-derivation): Take the device name for GRUB from

(qemu-initrd): Add 'file-systems' parameter, and remove #:mounts
parameter.

(mount-root-file-system): New procedure, with code formerly in
'boot-system'.
(mount-file-system): New procedure.
(boot-system): Add #:root-fs-type parameter. Remove 'MS_RDONLY' local
variable. Use 'mount-root-file-system' and 'mount-file-system'.
* doc/guix.texi (Using the Configuration System): Add 'file-system'
declaration.
* gnu/system/linux-initrd.scm (expression->initrd): Rename 'inputs'
parameter to 'to-copy'. Remove 'files-to-copy'. Rewrite 'builder' as
a gexp, and use 'gexp->derivation'.
(qemu-initrd): Adjust accordingly.

'guile-modules-in-chroot?' and 'mounts'. Change builder to simply
call 'boot-system'.
