Fixes <http://bugs.gnu.org/20037>.
Reported by 宋文武 <iyzsong@gmail.com> and Tomáš Čech.
* gnu/system.scm (operating-system-etc-directory): Remove call to
'delete-duplicates'.
* gnu/system/linux.scm (pam-services->directory)[builder]: Add call to
'delete-duplicates'.
* gnu/packages/admin.scm (wpa-supplicant-light): New variable containing the
previous dbus-free package, but renamed. Remove outdated TODO comments.
(wpa-supplicant): Now inherits from wpa-supplicant-light but adds dbus
support.
* gnu/system/install.scm (installation-os): Use wpa-supplicant-light.
This reverts commit 3b09332adf7ce8e976a4d117a62c586a53af04aa, 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?'.
* gnu/system/linux-initrd.scm (flat-linux-module-directory)[build-exp]:
Add 'lookup' procedure. Use 'recursive-module-dependencies' to
compute the list of modules to copy.
Adjust #:modules parameter.
* gnu/system/locale.scm: New file.
* gnu-system.am (GNU_SYSTEM_MODULES): Add it.
* gnu/system.scm (<operating-system>)[locale]: Change the default to
"en_US.utf8".
(operating-system-locale-directory): New procecure.
(operating-system-derivation): Use it.
* doc/guix.texi (Using the Configuration System): Change example locale
to "fr_FR.utf8".
(operating-system Reference): Add xref to "Locales". Document
'locale-definitions'.
(Locales): New section.
* po/guix/POTFILES.in: Add gnu/system.scm.
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/vm.scm (<file-system-mapping>): New record type.
(%store-mapping): New variable.
(host-9p-file-system): Rename to...
(mapping->file-system): ... this. Replace 'source' and 'target'
parameters with 'mapping'. Set 'flags' field.
(virtualized-operating-system): Add 'mappings' parameter and honor
it.
(system-qemu-image/shared-store-script): Add 'mappings' parameter.
Pass it to 'virtualized-operating-system'. Use it in argument to
'common-qemu-options'.
* gnu/system/vm.scm (file-system->mount-tag, host-9p-file-system): New
procedures.
(virtualized-operating-system): Use 'host-9p-file-system' for the
store.
(common-qemu-options): Add 'shared-fs' parameter.
[virtfs-option]: New procedure.
Use it.
(system-qemu-image/shared-store-script): Adjust accordingly.
* gnu/artwork.scm: New file.
* gnu-system.am (GNU_SYSTEM_MODULES): Add it.
* gnu/services/xorg.scm: Use it.
(%artwork-repository): Remove.
* gnu/system/grub.scm: Use it.
(%artwork-repository): Remove.
* gnu/services/base.scm (user-unmount-service): New procedure.
* gnu/system.scm (essential-services): Use it.
* gnu/system/install.scm (cow-store-service): Mention it in comment.
* gnu/system/grub.scm (<grub-image>, <grub-theme>): New record types.
(%artwork-repository, %background-image): New variables.
(<grub-configuration>)[theme]: New field.
(svg->png, resize-image, grub-background-image, eye-candy): New
procedures.
(grub-configuration-file): Use 'eye-candy' and add it in BUILDER.
* gnu/system/vm.scm (system-qemu-image/shared-store-script): Add "$@" at
the end of the script.
(common-qemu-options): Remove trailing newline.
* doc/guix.texi (Invoking guix system): Document it.
* gnu/system/vm.scm (system-qemu-image/shared-store): Add
#:disk-image-size and #:full-boot? parameters and honor them. Pass
'#:copy-inputs? full-boot?', and change #:inputs argument.
* guix/scripts/system.scm (system-derivation-for-action): Pass
#:disk-image-size to 'system-qemu-image/shared-store'.
* doc/guix.texi (Invoking guix system): Mention use of '--image-size' in
conjunction with '--full-boot'.
