This should be more efficient than loading the whole thing in user space.
* gnu/build/linux-modules.scm (load-linux-module*): Use
'load-linux-module/fd' instead of 'load-linux-module'. Remove 'slurp'.
Typically 'read-pid-file/container' would fail when starting services in
containers such as BitlBee.
* gnu/build/linux-container.scm (call-with-clean-exit): Use
'primitive-_exit' instead of 'primitive-exit'.
(container-excursion*): Close OUT.

* gnu/bootloader/extlinux.scm (install-extlinux): Factorize bootloader
writing in a new procedure write-file-on-device defined in (gnu build
bootloader).
* gnu/build/bootloader.scm: New file.
* gnu/local.mk (GNU_SYSTEM_MODULES): Add new file.
* gnu/system/vm.scm (qemu-img): Adapt to import and use (gnu build bootloader)
module during derivation building.
* gnu/scripts/system.scm (bootloader-installer-derivation): Ditto.
* 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.
Fixes a regression introduced in
c828969036 whereby /etc would no longer be
created as a result of calling 'mark-as-not-killable'.
This would affect ISO images because 'make-iso9660-image' does not
create /etc by default. In particular, the ISO installation image as
created by the "iso-image-installer" test would fail to boot while
creating the /root/etc/mtab symlink:
<https://hydra.gnu.org/build/2352514/nixlog/9/raw>.
* gnu/build/linux-boot.scm (mount-root-file-system): Make sure /root/etc
exists.
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".

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.
Previously we'd use "sendkey P" instead of "sendkey shift-p", which had
no effect.

'false-if-exception' instead of 'when (file-exists? ...)' to account
for dangling symlinks.
* gnu/build/activation.scm (%skeleton-directory): New variable.
(dot-or-dot-dot?, copy-account-skeletons): New procedure.
(add-user): Use 'copy-account-skeletons'.
(activate-etc): Use 'dot-or-dot-dot?'.
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.
* gnu/packages/patches/guile-linux-syscalls.patch (scm_load_linux_module):
Leave 'errno' unchanged when ERR != 0.
* gnu/build/linux-modules.scm (load-linux-module*): Check for the errno
value of ARGS to determine whether the module was already loaded.
* gnu/build/linux-boot.scm (mount-root-file-system): Remove 'catch #t'
around body. This was unneeded and even inconvenient because this
procedure is called from within 'call-with-error-handling' already.
* gnu/build/file-systems.scm (mount-file-system): When OPTIONS is false,
write "rw" to /etc/mtab. This fixes a bug whereby 'remove-from-mtab'
in (guix syscalls) would otherwise raise a 'match-error' because of
the missing field. This affected file systems mounted from the
initrd, such as devtmpfs, which has options == #f.
Reported by nebuli on #guix.
* gnu/build/vm.scm (initialize-partition-table): Add #:bootable?
parameter and honor it.
(initialize-hard-disk): Likewise.
* gnu/build/activation.scm (activate-firmware): New procedure.
* gnu/system.scm (<operating-system>)[firmware]: New field.
(directory-union): New procedure.
(%base-firmware): New variable.
(operating-system-activation-script): Use 'directory-union', and call
'activate-firmware'.
* doc/guix.texi (operating-system Reference): Document 'firmware'.
Fixes <http://bugs.gnu.org/18525>.
Reported by Mark H Weaver <mhw@netris.org>.
* gnu/build/activation.scm (activate-modprobe): New procedure.
* gnu/system.scm (modprobe-wrapper): New procedure.
(operating-system-activation-script): Use both.
* gnu/build/linux-boot.scm (boot-system): Add #:pre-mount parameter and
honor it.
* gnu/system/linux-initrd.scm (base-initrd): Add #:mapped-devices
parameter. Add 'device-mapping-commands' variable, and use it to
build the #:pre-mount argument of 'boot-system'.
* gnu/system.scm (mapped-device-user,
operating-system-user-mapped-devices,
operating-system-boot-mapped-devices): New procedures.
(device-mapping-services): Use 'operating-system-user-mapped-devices'
instead of 'operating-system-mapped-devices'.
(operating-system-initrd-file): Call the initrd with #:mapped-devices.
* gnu/build/activation.scm (activate-current-system): Honor
$GUIX_NEW_SYSTEM by default.
* guix/scripts/system.scm (switch-to-system): Set $GUIX_NEW_SYSTEM
before loading SCRIPT.
* gnu/build/install.scm (directives): Remove "/bin/sh".
* gnu/build/activation.scm (activate-/bin/sh): New procedure.
* gnu/system.scm (operating-system-activation-script): Use it.
Before that, 'sudo' would exit with:
sudo: /etc/sudoers is not a regular file
sudo: no valid sudoers sources found, quitting
* gnu/build/activation.scm (activate-etc): Check if SOURCE matches
'file-is-directory?'. If not, use 'copy-file' instead of 'symlink'.
* gnu/build/install.scm (evaluate-populate-directive): Wrap body in
"catch 'system-error", and report clear errors. In the symlink case,
retry up EEXIST.
(populate-root-file-system): Remove /var/guix/profiles/system-1-link
before attempting to create it.
* gnu/system/linux-initrd.scm (expression->initrd): Remove #:linux and
#:linux-modules parameters. Remove call to
'float-linux-module-directory'.
(base-initrd): Add call to 'float-linux-module-directory'. Use it in
#:linux-modules argument in the gexp. Remove #:linux and
#:linux-modules arguments to 'expression->initrd'.
* gnu/build/linux-initrd.scm (build-initrd): Remove
#:linux-module-directory parameter. Don't create 'modules'
sub-directory.
* gnu/build/linux-boot.scm (boot-system): Mentin that LINUX-MODULES is a
list of absolute file names. Don't prepend "/modules/" to
LINUX-MODULES.
* doc/guix.texi (Initial RAM Disk): Adjust accordingly.
* gnu/build/linux-initrd.scm (cache-compiled-file-name,
compile-to-cache, build-initrd): New procedures.
* gnu/system/linux-initrd.scm (expression->initrd)[builder]: Remove code
now moved above. Use 'build-initrd'.
* gnu/system/linux-initrd.scm (expression->initrd): Remove calls to
'imported-modules' and 'compiled-modules'. Use 'gexp->script' with
EXP. Add the result to TO-COPY. Make /init a symlink to that script,
and copy its closure into the "contents" directory. Add fake
/proc/self/exe symlink.
* gnu/build/linux-boot.scm (load-linux-module*): Add comment about mmap.
* gnu/system/vm.scm (system-qemu-image/shared-store-script): Add "-m
256". This turns out to be needed for initrds containing things like
e2fsck and several modules; with the default of 128 MiB, loading
libahci.ko may fail with -1.
