2020-11-05shepherd: Remove dependency on (guix utils)....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'. Ludovic Courtès
2020-09-21build: shepherd: Check for container support....Fixes: <https://issues.guix.gnu.org/43533>. * gnu/build/shepherd.scm (fork+exec-command/container): Check if containers are supported before joining PID namespaces. Mathieu Othacehe
2020-09-02installer: 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. * 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. Mathieu Othacehe
2020-06-12shepherd: '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. Ludovic Courtès
2020-06-12shepherd: 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'. Ludovic Courtès
2019-09-26shepherd: Ensure the log file has correct ownership....* gnu/build/shepherd.scm (make-forkexec-constructor/container): Ensure LOG-FILE has correct ownership. Ludovic Courtès
2019-09-26shepherd: 'make-forkexec-constructor/container' keeps the log file....* gnu/build/shepherd.scm (make-forkexec-constructor/container): Don't call 'clean-up' on LOG-FILE. This mirrors Shepherd commit 6892f638c78a14fedd075f664432757bc015c140. Ludovic Courtès
2019-09-12file-systems: Add /var/run/nscd to '%network-file-mappings'....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'. Ludovic Courtès
2019-05-03shepherd: Include /etc/localtime in service containers....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. Ludovic Courtès
2018-05-28system: Remove uses of the 'title' field of <file-system>....* 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. Ludovic Courtès
2017-11-22shepherd: Include /etc/group in service containers....* gnu/build/shepherd.scm (default-mounts)[passwd]: Rename to... [accounts]: ... this. Add /etc/group. Ludovic Courtès
2017-02-07Add (gnu build shepherd)....* gnu/build/shepherd.scm: New file. * gnu/local.mk (GNU_SYSTEM_MODULES): Add it. Ludovic Courtès
