Previously, services spawned with 'make-forkexec-constructor' &
co. would all inherit the environment variables of PID 1, which includes
things like 'BOOT_IMAGE'. This change resets it to the bare minimum.
* gnu/services/shepherd.scm (shepherd-configuration-file): Add call to
'default-environment-variables'. Remove 'setenv' call.
This reduces resident memory for PID 1 from 29.8MiB to 28.7MiB right
after boot on a bare-bones system (x86_64-linux).
* gnu/services/shepherd.scm (scm->go): New procedure.
(shepherd-configuration-file)[config]: Call it and use 'load-compiled'
instead of 'primitive-load'.
This hack worked around a defect in the Shepherd 0.5.0 and is no longer
needed.
* gnu/services/shepherd.scm (%containerized-shepherd-service): Remove.
* gnu/system/linux-container.scm (container-essential-services): Don't
use it.
* gnu/services/shepherd.scm (<shepherd-service>)[one-shot?]: New field.
(shepherd-service-file): Pass #:one-shot? to the <service> constructor.
* doc/guix.texi (Shepherd Services): Document it.
Fixes <https://bugs.gnu.org/23697>.
Reported by Jan Nieuwenhuizen <janneke@gnu.org>.
* gnu/build/file-systems.scm (check-file-system): Call 'start-repl' only
if current-input-port passes 'isatty?'.
* gnu/services/shepherd.scm (shepherd-configuration-file): After
'for-each' expression, call 'redirect-port'.
* gnu/tests/base.scm (run-basic-test)["stdin is /dev/null"]: New test.
This uses the 'replacement' service slot introduced in the Shepherd
version 0.5.0.
* gnu/services/shepherd.scm (shepherd-service-upgrade): Return a list of
services that need to be restarted to complete their upgrade.
* guix/scripts/system.scm (call-with-service-upgrade-info): Rename an internal
variable to reflect the change to shepherd-service-upgrade.
(upgrade-shepherd-services): Call 'load-services/safe' instead of
'load-services'. Print a message about services that need to be
manually restarted.
* gnu/services/herd.scm (load-services/safe): New procedure.
* doc/guix.texi (Invoking guix system): Document the new behaviour.

Suggested by atw on #guix.
* gnu/services/shepherd.scm (shepherd-service-file): Use 'scheme-file'
instead of 'gexp->file'.
(shepherd-configuration-file): Likewise, and adjust to non-monadic
style.
(shepherd-boot-gexp): Adjust accordingly.
* guix/scripts/system.scm (upgrade-shepherd-services): Use
'lower-object' in addition to 'shepherd-service-file'.
This fixes a bug whereby names of files defining services would be
invalid if 'provisions' contained more than one element.
* gnu/services/shepherd.scm (shepherd-service-file-name): Update
'match-lambda' accordingly.
