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
procedure.
Use it instead of 'strip-keyword-arguments'.
Fixes: <https://issues.guix.gnu.org/43533>.
* gnu/build/shepherd.scm (fork+exec-command/container): Check if containers
are supported before joining PID namespaces.
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.
* gnu/installer/final.scm (umount-cow-store): Remove it,
(install-system): run the installation from within a container.
* gnu/installer/newt/final.scm (run-install-shell): Remove the display hack.
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.
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'.
This allows containers created by "guix environment -CN" or by
"guix system container -N" to talk to the host nscd.
* gnu/system/file-systems.scm (%network-file-mappings): Add
"/var/run/nscd".
* gnu/build/shepherd.scm (default-mounts)[nscd-socket]: Remove.
* gnu/system/linux-container.scm (container-script)[nscd-run-directory]
[nscd-mapping, nscd-os, nscd-specs]: Remove.
[script]: Filter out from SPECS bind-mounts where the device does not
exist.
* guix/scripts/environment.scm (launch-environment/container)
[optional-mapping->fs]: New procedure.
[mappings]: Remove %NETWORK-FILE-MAPPINGS.
[file-systems]: Add %NETWORK-FILE-MAPPINGS here, filtered through
'optional-mapping->fs'.
Fixes a bug whereby Tor (for example) would emit syslog messages with a
UTC timestamp instead of local time.
* gnu/build/shepherd.scm (default-mounts): Add /etc/localtime to
MAPPINGS.
