I dediced to keep adding /tmp as tmpfs since I was not able to trigger bug
while still using unionfs, so I could not verify whether this mount is still
needed with overlayfs. Mapping /tmp to tmpfs does not harm, so we are on the
save side.
* gnu/system/install.scm (make-cow-store): Mount /gnu/store without additional
read-only bind-mount, since in overlayfs the "lower" level is always
read-only. Add work-dir required by overlayfs. No need to sleep anymore
since now using the mount syscall. [unionfs]: Remove now unused function.
(%installation-services): Update comment.
(installation-os)[file-systems]: Update comment.
Overlayfs is part of the kernel, while unionfs needs FUSE. This also reduces
the size of the initrd by ca. 4.3% (487K).
* gnu/build/linux-boot.scm (mount-root-file-system): Remove optional parameter
"unionfs"; mount using overlayfs instead of unionfs; new directory layout
requied by overlayfs; update documentation.
[mark-as-not-killable]: Remove now unused function
* gnu/system/linux-initrd.scm (file-system-packages): Remove now unused
packages "unionfs-fuse/static" and thus unused related 'if'.
(linux-modules): Replace "fuse" by "overlay".
* gnu/system/vm.scm (operating-system-uuid): Use 2^32 - 1 instead of
2^32 as hash size.
On some 32 bit system (ARM for example), 2^32 exceeds hash max
size (ULONG_MAX = 2^32 - 1).
* gnu/system/examples/lightweight-desktop.tmpl <file-systems>: Add a
UUID for the /boot/efi partition.
* doc/guix.texi (Using the Configuration System): Mention it.
Reported by Roel Janssen <roel@gnu.org>
at <https://lists.gnu.org/archive/html/help-guix/2017-09/msg00094.html>.
* 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?'.
* gnu/build/file-systems.scm (mount-file-system): Rename 'spec' to 'fs'
and assume it's a <file-system>.
* gnu/build/linux-boot.scm (boot-system): Assume MOUNTS is a list of
<file-system> and adjust accordingly.
* gnu/build/linux-container.scm (mount-file-systems): Remove
'file-system->spec' call.
* gnu/services/base.scm (file-system-shepherd-service): Add
'spec->file-system' call. Add (gnu system file-systems) to 'modules'.
* gnu/system/linux-initrd.scm (raw-initrd): Use (gnu system
file-systems). Add 'spec->file-system' call for #:mounts.
By referencing guile from the initrd output explicitly, it will be present in
the store when this initrd is used. If the exact guile used within the initrd
isn't present in the store, then after root is switched during the boot
process, loading modules (such as (ice-9 popen)) won't work.
This fixes guix-patches bug #28399, "Fix mysql activation, and add a basic
test".
* gnu/system/linux-initrd.scm (expression->initrd)[builder]: Write out a file
called references in to the initrd output, which includes the store path for
guile.
* gnu/system/uuid.scm (uuid=?): New procedure.
* tests/uuid.scm ("uuid=?"): New test.
* gnu/build/file-systems.scm (partition-uuid-predicate)
(luks-partition-uuid-predicate): Use it instead of 'bytevector=?'.
* gnu/system/vm.scm (qemu-image): When guessing the root-size, use a lower
bound of 20 MiB, otherwise the root file system size is sometimes 0 MiB in
size.
* gnu/system/uuid.scm (%fat32-uuid-rx): New variable.
(string->fat32-uuid): New procedure.
(%uuid-parsers): Add it.
* tests/uuid.scm ("uuid, FAT32, format preserved"): New test.
This makes collisions less likely than when using a label to look up the
partition. See <https://bugs.gnu.org/27735>.
* gnu/system/vm.scm (operating-system-uuid): New procedure.
(system-disk-image): Define 'root-uuid' and use it for the root file
system. Pass it to 'iso9660-image' and 'qemu-image'.
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 (<bootloader-configuration>): Deprecate "device" field in
favor of "target" field. This is mostly a renaming but also a generalization
to support UEFI targets being paths to a mounted partition instead of a device
name.
* gnu/system/examples/bare-bones.tmpl:
* gnu/system/examples/desktop.tmpl:
* gnu/system/examples/lightweight-desktop.tmpl:

* guix/scripts/system.scm (perform-action): Rename device argument to
bootloader-target.
(process-action): Adapt caller.

* gnu/bootloader/grub.scm (install-grub-efi): Fix grub-install invocation for
EFI systems.
* gnu/system/examples/bare-bones.tmpl: Use the newer
"bootloader-configuration" syntax.
* gnu/system/examples/desktop.tmpl: Use bootloader-configuration sytax. Also,
use the same label for the LUKS-mapped device and the root partition. Remove
unneeded "title" field for the file-system based on LUKS; as noted in the
manual, the "title" field is ignored for mapped devices.
* gnu/system/examples/lightweight-desktop.tmpl: Use bootloader-configuration,
and use grub-efi-bootloader.
* gnu/system/vm.scm (system-qemu-image/shared-store-script): Add
#:options parameter and honor it.
(<virtual-machine>): New record type.
(virtual-machine): New macro.
(port-forwardings->qemu-options, virtual-machine-compiler): New
procedures.
* gnu/system/vm.scm (expression->derivation-in-linux-vm): Add
#:single-file-output? and pass it to 'load-in-linux-vm'.
(iso9660-image): Pass #:single-file-output? to
'expression->derivation-in-linux-vm'.
* gnu/build/vm.scm (load-in-linux-vm): Add #:single-file-output? and
honor it.
* gnu/system/locale.scm (single-locale-directory): Use 'computed-file'
instead of 'gexp->derivation'.
(locale-directory): Adjust accordingly and do the same.
* gnu/system.scm (operating-system-directory-base-entries): Adjust
accordingly.
* gnu/build/vm.scm (initialize-hard-disk): Use "GuixSD" as label.
* gnu/system/install.scm (installation-os): Use "GuixSD" as label.

label.

'gexp->derivation'.
(raw-initrd): Adjust accordingly.
* build-aux/hydra/gnu-system.scm (qemu-jobs): Add 'iso9660-image .
* gnu/build/vm.scm (make-iso9660-image): New variable. Export it.

* gnu/system/vm.scm (expression->derivation-in-linux-vm):
Change #:disk-image-size default to 'guess.
[builder]: When DISK-IMAGE-SIZE is 'guess, use
'estimated-partition-size' and compute and estimate of the image size.

'guess.
