* gnu/system/file-systems.scm (file-system->spec): When DEVICE is a
UUID, serialize it in a way that preserves its type.
(spec->file-system): Adjust accordingly.
* gnu/build/file-systems.scm (canonicalize-device-spec): Add case for
when SPEC is 'uuid?'.
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
docstring.
* gnu/services/base.scm: Use it.
* tests/file-systems.scm ("does not pull (gnu packages …)"): New test.
* gnu/system/linux-initrd.scm (base-initrd): Move helper-packages body to ...
* gnu/system/file-systems.scm (file-system-packages): ... here. New variable.
Also export it.
(gnu system file-systems) is used on the "build" side since commit
5970e8e248.

(%store-prefix): New procedure.
* tests/file-systems.scm ("does not pull (guix config)"): New test.
Suggested by John Darrington <john@darrington.wattle.id.au>.

(file-prefix?): New procedure.
(file-system-needed-for-boot?): Use it to check whether FS holds the
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.
* gnu/system/file-systems.scm (spec->file-system): New procedure.
* gnu/system/linux-container.scm (container-script)[script]: Call
'spec->file-system' inside gexp.

Fixes <http://bugs.gnu.org/22176>.

* gnu/system/file-systems.scm (<file-system>)[mount?]: New field.

dependency->dmd-service-name): New procedures.
(file-system-service-type): Use it.
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.
(mount-root-file-system): Mount /rw-root/dev as a devtmpfs instead of
calling 'make-essential-device-nodes'.

* doc/guix.texi (File Systems): Adjust accordingly.

(uuid): New macro.
* tests/file-systems.scm: New file.
* Makefile.am (SCM_TESTS): Add it.
* doc/guix.texi (File Systems): Give an example of UUID.
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.
* gnu/system.scm (other-file-system-services)[file-systems]: Rely on
'file-system-needed-for-boot?' to handle the "/" case.
(operating-system-initrd-file)[boot-file-systems]: Likewise.
* gnu/system/file-systems.scm (<mapped-device-type>): New record type.

parameter to 'open'. Add 'close' parameter and honor it.
* gnu/system.scm (luks-device-mapping): Rename to...
(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/system/file-systems.scm (<mapped-device>): New record type.
* gnu/system.scm (<operating-system>)[mapped-devices]: New field.
(luks-device-mapping): New procedure.
(other-file-system-services)[device-mappings, requirements]: New
procedures. Pass #:requirements to 'file-system-service'.
(device-mapping-services): New procedure.
(essential-services): Use it. Append its result to the return value.
(operating-system-initrd-file): Add comment.
* 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.
Suggested by Mark H. Weaver.

(%base-groups): Introduce 'system-group' macro, and use it.
* gnu/system.scm (user-group->gexp): Pass the 'system?' field.
* guix/build/activation.scm (add-group): Add #:system? and honor it.
(activate-users+groups): Handle the 'system?' field.
* gnu/system/file-systems.scm (%tty-gid): Choose an ID below 1000.

* gnu/system/file-systems.scm (<file-system>)[title]: New field.
* 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.
* build-aux/hydra/demo-os.scm, gnu/system/linux-initrd.scm,
gnu/system/vm.scm: Use it.
