The 'title' field was easily overlooked and was an endless source of
confusion. Now, the value of the 'device' field is self-contained.

field. Rewrite documentation of 'device' and document
'file-system-label'.
* gnu/system/file-systems.scm (<file-system>): Do not export.
* gnu/system.scm (operating-system-root-file-system): Use an accessor
instead of 'match'.
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.
* gnu/system.scm (<operating-system>)[initrd-modules]: New field.

* gnu/tests/install.scm (%raid-root-os): Likewise.
* doc/guix.texi (operating-system Reference): Add 'initrd-modules'.
(Initial RAM Disk): Document it. Adjust example to not use
#:extra-modules.
This simplifies OS configuration: users no longer need to be aware of
what a given service depends on.

Fixes a regression introduced in
commit 075681d350.
* gnu/system.scm (read-boot-parameters): For 'root-device', use
'device-sexp->device', not 'device->sexp'.
* gnu/system.scm (read-boot-parameters)[device->sexp]: New procedure.
Use it for 'root-device' and 'store-device'.
(device->sexp): Serialize the UUID type in addition to its bytevector.
Conceptually a UUID is just a bytevector. However, there's software out
there such as GRUB that relies on the string representation of different
UUID types (e.g., the string representation of DCE UUIDs differs from
that of ISO-9660 UUIDs, even if they are actually bytevectors of the
same length). This new <uuid> record type allows us to preserve
information about the type of UUID so we can eventually convert it to a
string using the right representation.
* gnu/system/uuid.scm (<uuid>): New record type.
(bytevector->uuid): New procedure.
(uuid): Return calls to 'make-uuid'.
(uuid->string): Rewrite using 'match-lambda*' to accept a single 'uuid?'
argument.
* gnu/bootloader/grub.scm (grub-root-search): Check for 'uuid?' instead
of 'bytevector?'.
* gnu/system.scm (bootable-kernel-arguments): Check whether ROOT-DEVICE
is 'uuid?'.
(read-boot-parameters): Use 'bytevector->uuid' when the
store device is a bytevector.
(read-boot-parameters-file): Check for 'uuid?' instead of 'bytevector?'.
(device->sexp): New procedure.
(operating-system-boot-parameters-file): Use it for 'root-device' and
'store'.
(operating-system-bootcfg): Remove conditional in definition of
'root-device'.
* gnu/system/file-systems.scm (file-system->spec): Check for 'uuid?' on
DEVICE and take its bytevector.
* gnu/system/mapped-devices.scm (open-luks-device): Likewise.
* gnu/system/vm.scm (iso9660-image): Call 'uuid-bytevector' for the
#:volume-uuid argument.
* gnu/bootloader.scm (menu-entry-device-mount-point): New variable. Export it.
(<menu-entry>: New field "device".
* gnu/bootloader/grub.scm (grub-confgiuration-file): Handle <menu-entry>
entries.
* gnu/bootloader/extlinux.scm (extlinux-configuration-file): Handle
<menu-entry> entries.

(operating-system-bootcfg): Make OLD-ENTRIES a list of <menu-entry>.
* guix/script/system.scm (reinstall-bootloader): Fix bootcfg usage.
(perform-action): Fix bootcfg usage.
* gnu/packages/linux.scm (linux-libre)[arguments]: Add to the regex to
find and install the aarch64-linux kernel.
* gnu/system.scm (system-linux-image-file-name): Add entry for aarch64.

instead of 'gexp->derivation'.
(locale-directory): Adjust accordingly and do the same.
* gnu/system.scm (operating-system-directory-base-entries): Adjust
accordingly.
