2022-05-01Add (guix least-authority).Ludovic Courtès
* guix/least-authority.scm: New file. * Makefile.am (MODULES): Add it. * gnu/build/shepherd.scm (default-mounts): Make public.
2022-04-12shepherd: Add #:supplementary-groups.Leo Nikkilä
To support the argument introduced in Shepherd 0.9.0 when defining container-bound services. * gnu/build/shepherd.scm (exec-command*) (make-forkexec-constructor/container): Add '#:supplementary-groups'. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
2022-04-11shepherd: 'fork+exec-command/container' always returns a PID.Ludovic Courtès
Fixes a regression introduced in 938448bf40fc77092859352d2243e2d0c236375f whereby 'fork+exec-command/container' would return #t, then used as the running value of the 'guix-daemon' service in the installer. Upon installation completion, stopping the 'guix-daemon' service would fail with wrong-type-arg because that #t would be passed to the 'stop' method in lieu of a PID. * gnu/build/shepherd.scm (fork+exec-command/container): Return a PID rather than #t.
2022-04-11shepherd: 'exec-command*' has a valid default #:directory.Ludovic Courtès
Fixes a regression introduced in 938448bf40fc77092859352d2243e2d0c236375f where 'exec-command*' could get #:directory #f, in particular when called by 'fork+exec-command/container'. * gnu/build/shepherd.scm (exec-command*): Add default value for #:directory.
2022-04-07shepherd: Adjust 'fork+exec-command/container' for the Shepherd 0.9.Ludovic Courtès
* gnu/build/shepherd.scm (exec-command*): New procedure, with code formerly... (make-forkexec-constructor/container): ... here. Use it. (fork+exec-command/container): Use 'fork+exec-command' only when CONTAINER-SUPPORT? is false or PID is the current process.
2021-08-02build: shepherd: Use autoload to lazily bind Shepherd modules.Maxim Cournoyer
Instead of imperative module-autoload! directives. * gnu/build/shepherd.scm: Replace module-autoload! directives by autoload arguments for define-module.
2020-11-05shepherd: Remove dependency on (guix utils).Ludovic Courtès
Since commit 8ce6f4dc2879919c12bc76a2f4b01200af97e019, 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'.
2020-09-21build: shepherd: Check for container support.Mathieu Othacehe
Fixes: <https://issues.guix.gnu.org/43533>. * gnu/build/shepherd.scm (fork+exec-command/container): Check if containers are supported before joining PID namespaces.
2020-09-02installer: Run the installation inside a container.Mathieu Othacehe
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.
2020-06-12shepherd: 'read-pid-file/container' terminates the whole process group.Ludovic Courtès
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.
2020-06-12shepherd: Unblock signals in the child process.Ludovic Courtès
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'.
2019-09-26shepherd: Ensure the log file has correct ownership.Ludovic Courtès
* gnu/build/shepherd.scm (make-forkexec-constructor/container): Ensure LOG-FILE has correct ownership.
2019-09-26shepherd: 'make-forkexec-constructor/container' keeps the log file.Ludovic Courtès
* gnu/build/shepherd.scm (make-forkexec-constructor/container): Don't call 'clean-up' on LOG-FILE. This mirrors Shepherd commit 6892f638c78a14fedd075f664432757bc015c140.
2019-09-12file-systems: Add /var/run/nscd to '%network-file-mappings'.Ludovic Courtès
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'.
2019-05-03shepherd: Include /etc/localtime in service containers.Ludovic Courtès
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.
2018-05-28system: Remove uses of the 'title' field of <file-system>.Ludovic Courtès
* gnu/system/install.scm (installation-os): Remove uses of the 'title' field of 'file-system'; use 'file-system-label' as appropriate. * gnu/system/vm.scm (system-disk-image, system-qemu-image): Likewise. * gnu/tests.scm (%simple-os): Likewise. * gnu/tests/install.scm (%minimal-os, %minimal-extlinux-os) (%minimal-os-on-vda, %separate-home-os, %separate-store-os) (%raid-root-os, %encrypted-root-os, %btrfs-root-os): Likewise. * gnu/build/shepherd.scm (default-mounts)[tmpfs]: Likewise. * tests/guix-system.sh: Likewise. * tests/system.scm (%root-fs): Likewise. ("operating-system-boot-mapped-devices, implicit dependency"): Likewise.
2017-11-22shepherd: Include /etc/group in service containers.Ludovic Courtès
* gnu/build/shepherd.scm (default-mounts)[passwd]: Rename to... [accounts]: ... this. Add /etc/group.
2017-02-07Add (gnu build shepherd).Ludovic Courtès
* gnu/build/shepherd.scm: New file. * gnu/local.mk (GNU_SYSTEM_MODULES): Add it.
