* gnu/build/vm.scm (load-in-linux-vm): Make a shared temporary directory
available in the VM.
* gnu/system/vm.scm (%linux-vm-file-systems): Add a corresponding entry.
* gnu/build/vm.scm (load-in-linux-vm): New argument #:target-arm32.
Use it to adapt command for qemu-system-arm. This implies to choose a
machine ("virt"), use the correct console port "ttyAMA0", disable KVM use
that is buggy on some ARM boards (Odroid XU4 for example) and use user mode
network stack instead of NIC. Gather all those options in a new variable
"arch-specific-flags".
* gnu/system/vm.scm (expression->derivation-in-linux-vm): Pass
to load-in-linux-vm "#:target-arm32?" argument.
* gnu/build/vm.scm (make-iso9660-image): Call
'populate-root-file-system' instead of a series of 'mkdir-p' calls. Add
/etc to the arguments of xorriso.
* gnu/build/vm.scm (<partition>)[uuid]: New field.
(create-ext-file-system): Add #:uuid and honor it.
(create-fat-file-system): Add #:uuid.
(format-partition): Add #:uuid and honor it.
(initialize-partition): Honor the 'uuid' field of PARTITION.
This is used in the installation process, as the mountpoint for the target
filesystem.
* gnu/build/vm.scm (make-iso9660-image): Create /mnt within the generated ISO
image.
This mimics the functionality in the root-partition-initializer used in
creating the QEMU image. This helps when trying to run guix system init from
the generated ISO image.
* gnu/build/vm.scm (make-iso9660-image): Add support for registering closures.
* 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/build/vm.scm (initialize-hard-disk): Use "GuixSD" as label.
* gnu/system/install.scm (installation-os): Use "GuixSD" as label.
* gnu/system/vm.scm (system-disk-image): Use "GuixSD" or "GUIXSD" as volume
label.

* 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 (iso9660-image): New variable. Use make-iso9660-image.
(system-disk-image): Use iso9660-image.
* gnu/build/vm.scm (estimated-partition-size): New procedure.
* 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.
(qemu-image): Likewise.
* guix/build/store-copy.scm (file-size, closure-size): New procedures.
* guix/scripts/system.scm (%default-options): Change 'image-size' to
'guess.
* doc/guix.texi (Building the Installation Image): Remove '--image-size'
flag from example.
(Invoking guix system): Document the image size estimate.
* gnu/build/vm.scm (load-in-linux-vm): Add 'format' call when
MAKE-DISK-IMAGE? is true.
(initialize-partition-table): Show the size of the partitions being
created.
* gnu/build/vm.scm (define-module): Use module (guix build syscalls).
It fixes the following warnings during guix build :
gnu/build/vm.scm:233:3: warning: possibly unbound variable `mount'
gnu/build/vm.scm:238:3: warning: possibly unbound variable `umount'
gnu/build/vm.scm:268:8: warning: possibly unbound variable `mount'
gnu/build/vm.scm:276:8: warning: possibly unbound variable `umount'
gnu/build/vm.scm:315:4: warning: possibly unbound variable `mount'
gnu/build/vm.scm:323:4: warning: possibly unbound variable `umount'
This was not possible until the previous commit because we had to be sure
that Guile core implementation of 'mount' and 'umount' was used in
initrd context.

Fixes <http://bugs.gnu.org/22633>.
* gnu/build/vm.scm (load-in-linux-vm): Only pass "-enable-kvm" flag to qemu
if "/dev/kvm" is present.
* gnu/system/vm.scm (common-kvm-options): Same as above.
* gnu/build/vm.scm (<partition>): New record type.
(fold2): New procedure.
(initialize-partition-table): Remove #:bootable? and
'partition-size' parameters. Add 'partitions' parameter. Invoke 'parted'
with '--script'.
(initialize-root-partition): Remove.
(initialize-partition, root-partition-initializer): New procedures.
(initialize-hard-disk): Remove #:system-directory, #:disk-image-size,
#:file-system-type, #:file-system-label, #:closures, #:copy-closures?,
#:bootable?, and #:register-closures? parameters. Add #:partitions.
Rewrite to use 'initialize-partition' for each item of PARTITIONS.
* gnu/system/vm.scm (expression->derivation-in-linux-vm): Add (guix records)
to #:modules default value.
(qemu-image): Adjust accordingly.
* gnu/build/vm.scm (initialize-root-partition, initialize-hard-disk): Use the
'umount' procedure instead of invoking the 'umount' command.
* gnu/system/vm.scm (qemu-image): Remove UTIL-LINUX from INPUTS.
This would not work when /boot is a separate partition, as reported by
Nikita Karetnikov <nikita@karetnikov.org> in <http://bugs.gnu.org/19220>.
This fixes a regression introduced in 39d1f82.
* gnu/build/install.scm (install-grub): Copy GRUB.CFG instead of
symlinking it, as was the case before 39d1f82.
* gnu/build/vm.scm (register-grub.cfg-root): Add 'grub.cfg' parameter.
Make it a permanent GC root instead of an indirect GC root.
(initialize-hard-disk): Adjust accordingly.
* guix/scripts/system.scm (install-grub*): Replace use of
'add-indirect-root' by the addition of a permanent GC root in
%GC-ROOTS-DIRECTORY.
Fixes <http://bugs.gnu.org/19160>.
* guix/scripts/system.scm (install-grub*): Make /boot/grub/grub.cfg an
indirect GC root.
* gnu/build/install.scm (install-grub): Make TARGET a symlink.
* gnu/build/vm.scm (register-grub.cfg-root): New procedure.
(initialize-hard-disk): Use it.
Reported by nebuli on #guix.

parameter and honor it.
