store-copy: 'populate-store' can optionally deduplicate files.
Until now deduplication was performed as an additional pass after
copying files, which involve re-traversing all the files that had just
been copied.

store-copy: 'populate-store' resets timestamps.
Until now, 'populate-store' would reset permissions but not timestamps,
so callers would resort to going through an extra directory traversal to
reset timestamps.

shepherd: Remove dependency on (guix utils).
Since commit 8ce6f4dc28, importing this
module in a gexp would pull in (guix config) from the host, thereby
leading to non-reproducible derivations.  Users in (gnu services ...) do
not expect that so simply remove the (guix utils) dependency for now.

* gnu/build/shepherd.scm (fork+exec-command/container)[strip-pid]: New

This is a follow-up of f19cf27c2b. The

services: secret-service: Add initial client/server handshake.
This allows the client running on the host to know when it's actually
connect to the server running in the guest.  Failing that, the client
would connect right away to QEMU and send secrets even though the server
is not running yet in the guest, which is unreliable.

* gnu/build/secret-service.scm (secret-service-send-secrets): Add
 #:handshake-timeout.  Read from SOCK an initial message from the
server.  Return #f on error.

Mathieu Othacehe 8ce6f4dc28
installer: Run the installation inside a container.
When the store overlay is mounted, other processes such as kmscon, udev
and guix-daemon may open files from the store, preventing the
underlying install support from being umounted. See:
https://lists.gnu.org/archive/html/guix-devel/2018-12/msg00161.html.

To avoid this situation, mount the store overlay inside a container,
and run the installation from within that container.

* gnu/build/shepherd.scm (fork+exec-command/container): New procedure.
* gnu/services/base.scm (guix-shepherd-service): Support an optional PID
argument passed to the "start" method. If that argument is passed, ensure that
guix-daemon enters the given PID MNT namespace by using
fork+exec-command/container procedure.

linux-libre: Support module compression.
This commit adds support for GZIP compression for linux-libre kernel
modules. The initrd modules are kept uncompressed as the initrd is already
compressed as a whole.

The linux-libre kernel also supports XZ compression, but as Guix does not have
any available bindings for now, and the compression time is far more
significant, GZIP seems to be a better option.

system: image: Remove "image-root" when building raw disk-images.
The "image-root" derivation output is used as a temporary directory that is
passed to mke2fs and mkdosfs later on. By merging the creation of this
directory and the production of partition images, we can get rid of the
derivation.

As mke2fs and mkdosfs are not able to override file permissions, call those
commands with fakeroot. This way, all the image files will be owned by root,
even if image generation is done in an unprivilegded context.

* gnu/system/image.scm (system-disk-image): Merge "image-root" and
"iso9660-image" derivations so that we spare an extra derivation. Also add

shepherd: 'read-pid-file/container' terminates the whole process group.
This mirrors a change made in the Shepherd 0.8.0.  Previously, upon
startup failure, we could have left processes behind.

* gnu/build/shepherd.scm (read-pid-file/container): Kill (- PID) instead
of PID.

shepherd: Unblock signals in the child process.
Fixes <https://bugs.gnu.org/41791>.
Reported by Tobias Geerinckx-Rice <me@tobias.gr>.

This change mirrors changes made in the Shepherd 0.8.1, where signals
are blocked in the shepherd process in support of 'signalfd'.  The
regression was introduced with the switch to 0.8.1 in
3f9c62d1a8b345909adaeb22f454ad22554c55a1: child processes would not
receive SIGTERM upon 'herd stop SERVICE'.

* gnu/build/shepherd.scm <top level>: Autoload (shepherd system).
(make-forkexec-constructor/container): Call call to 'sigaction' and
'unblock-signals'.

build: image: Do not call make-essential-device-nodes by default.
Calling "mknod" without root permissions fails. Plus those device nodes do not
appear to be needed to boot.

* gnu/build/image.scm (initialize-root-partition): Do not use
make-essential-device-nodes as default make-device-nodes procedure.
