s6-scripts

• s6-contrib: Artix's s6-contrib (pregenerated, with a few patches, see _patches)

• s6-rc (/etc/s6-rc): Service definitions for s6-rc

  • adminsv (/etc/s6-rc/adminsv): User-modifiable service directory, contains the default service containing the boot service. Can be extended with user-written services.

  • config (/etc/s6-rc/config): Per-service configuration, eg. logging, args, ...

  • sv (/etc/s6-rc/sv -> /usr/share/s6-sv, amalgamated)

    • bundles: Various convenience bundles that servies can depend upon

      • boot: Depends on misc, mount, setup

      • misc: Guarantees the following:

        • The device manager (mdevd) is up, and coldplug events have been processed

        • Any modules listed in /etc/modules have been loaded

      • mount: Guarantees that the following filesystems are mounted:

        • cgroups (/sys/fs/cgroup or /sys/fs/cgroup/unified)

        • devtmpfs (/dev)

        • tmpfs (/tmp)

        • procfs (/proc)

        • sysfs (/sys)

        • User filesystems and swap defined in /etc/fstab

      • setup: Most services would want to depend on this. Guarantees the following:

        • Cleanup actions have been performed, eg. removing /etc/nologin

        • Consoles have been setup according to /etc/vconsole.conf

        • The hostname has been setup according to /etc/hostname

        • The loopback device (lo) has been setup

        • /dev/urandom has been seeded with /var/lib/random-seed

        • / has been remounted rw (doesn't guarantee that /home or similar paths have been mounted if located on different filesystems, depend on mount or mount-filesystems for that)

        • /dev, /proc and /sys have been mounted

        • The sysctl config has been loaded

    • core: Core services required for a working system

      • cleanup

      • coldplug

      • console-setup
