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.
Fixes a regression introduced in
7208995426 whereby (gnu system
file-systems) would pull in (gnu packages …) module, which in turn
breaks when importing things like (gnu build shepherd).
* gnu/system/file-systems.scm (file-system-type-predicate): Export.
(file-system-packages): Move to...
* gnu/system/linux-initrd.scm (file-system-packages): ... here. Add

store.
* tests/file-systems.scm ("file-system-needed-for-boot?"): New test.
* gnu/tests/install.scm (%separate-store-os)[file-systems]: Remove
'needed-for-boot?' field for "/gnu".
* gnu/build/linux-container.scm (mount-file-systems): 'mounts' is now a
list of <file-system> objects instead of a list of lists ("specs").
Add call to 'file-system->spec' as the argument to 'mount-file-system'.
(run-container, call-with-container): Adjust docstring accordingly.

Suggested by Petter <petter@mykolab.ch>
and Mark H Weaver <mhw@netris.org>.
Reported by Duncan Keall <duncan@duncankeall.com>.
Partly fixes <http://bugs.gnu.org/19190> by populating /dev/mapper
early enough.
* gnu/build/linux-boot.scm (mount-essential-file-systems): Mount /dev as
a devtmpfs.
(move-essential-file-systems): Add /dev.

This reverts commit 3b09332adf, which
turned out to be a bad idea because we need to have dependency
information between the device-mapping service and the file-system
service that uses it.
* gnu/system/file-systems.scm (<mapped-device>)[needed-for-boot?]: New
field.
* gnu/system.scm (operating-system-user-mapped-devices,
operating-system-boot-mapped-devices): Use it instead of trying to
guess. Guessing doesn't work when one refers to a partition using its
label, for instance.
* doc/guix.texi (Mapped Devices): Document 'needed-for-boot?'.
Reported by Nikita Karetnikov.
* gnu/system/file-systems.scm (<file-system>): Rename 'needed-for-boot?'
accessor to '%file-system-needed-for-boot?'.
(file-system-needed-for-boot?): New inlinable procedure.

(open-luks-device): ... this.
(close-luks-device): New procedure.
(luks-device-mapping): New variable.
(device-mapping-services): Get the type of MD, and pass its 'open' and
'close' fields to 'device-mapping-service'.

* gnu/services/base.scm (file-system-service): Add #:title parameter.
In 'start' gexp, use 'canonicalize-device-spec' and honor TITLE.
* gnu/system.scm (other-file-system-services,
operating-system-root-file-system, operating-system-initrd-file):
Adjust accordingly.
* gnu/system/linux-initrd.scm (file-system->spec): Likewise.
* gnu/system/vm.scm (system-disk-image): Add 'title' field for the root
file system.
* guix/build/linux-initrd.scm (mount-file-system): Expect the second
element of SPEC to be the title.
(boot-system)[root-mount-point?, root-fs-type]: Likewise.
* 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.
