ABOUT:
org.bus1.activator: The system service activator. It sets up
bus connection for services and executes them on-demand.
- sets up the service environment:
- a new mount namespace
- a separate tmpfs /
- mounts the kernel filesystems
- mounts /usr with the system image
- mounts /var with the /var/bus1/<service> data directory
- starts org.bus1.devices
org.bus1.coredump: A crash handler which logs a stack trace of a failing
process.
- called by the kernel when a process crashes
- writes stacktrace to the kernel log buffer
- optionally writes the core file to /var/coredump/<user id>-<escaped binary name>
org.bus1.devices: The hotplug device manager and kernel module loading
service.
- listens to kernel uevents
- crawls /sys for coldplug
- adjusts platform permissions in /dev
- loads kernel modules for plugged devices
org.bus1.diskctl: A command line tool to manage signed and encrypted
disk volumes.
- adds a metadata header to a filesystem image and creates a
cryptographic hash tree to provide data integrity validation;
used for the org.bus1.disk.system image mounted at /usr
- adds a metadata header for an encrypted volume; used for the
org.bus1.disk.data volume mounted at /var
org.bus1.login: This simple example of the org.bus1.administrator
just starts a tty and a serial console login shell. It is executed
by the symlink org.bus1.administrator.
- starts a tty login if /dev/tty1 exists
- starts a serial console if console=<device> is given on the kernel
command line
org.bus1.init: The init process PID1.
- resets the loader boot counter on successful bootup
- starts org.bus1.activator
org.bus1.rdinit: The init process PID1 in the initrd, symlinked from /init.
- mounts /dev, /sys, /proc, /dev/pts, /sys/fs/bus1
- starts org.bus1.acvitvator
- starts org.bus1.devices
- reads the kernel commandline:
- disk=<UUID> locates the disk with the given GPT UUID
- the first EFI System Partition
- the first GPT partition with the type UUID of
e0243462-d2d0-4c3b-ad28-b365f2da3b4d
- as an alternative it locates the devices:
- boot=/dev/<device>
- data=/dev/<device>
- mounts the boot partition to /boot (r/o)
- sets up verification of the system image named <release>.img
- mounts the system image to /usr
- the image is located relative to the
loader=<path to boot loader> variable
- as an alternative is is located in the /boot
root directory
- sets up decryption of the data partition
- mounts the data partition to /var
- executes org.bus1.init
