Command and output examples

The command 66-intree boot, run as root user, on Obarun's default system displays the following where boot is the tree used to properly boot the machine:

   
    Name        : boot
    Initialized : yes
    Enabled     : no
    Current     : no
    Contains    : tty12  system-hostname  mount-run  populate-run  mount-tmp  populate-tmp  mount-proc  mount-sys
                  populate-sys  mount-dev  mount-pts  mount-shm  populate-dev  mount-cgroups  00  modules-kernel  udevd
                  udevadm  devices-crypttab  system-hwclock  system-random  modules-system  system-sysctl
                  system-fontnkey  devices-dmraid  devices-btrfs  devices-lvm  devices-zfs  system-Devices  mount-swap
                  all-Mount  system-fsck  mount-fstab  all-System  mount-rw  local-iptables  local-ip6tables  local-loop
                  local-sethostname  local-time  local-authfiles  local-tmpfiles  local-rc  local-dmesg  all-Local
                  all-Runtime  All

	

The field name gives you the name of the tree.

The field Initialized tells you if the tree was initialized with 66-init tool.

The field Enabled reveals the state of the tree—see 66-tree -E.

The field Current tells you if the tree is the current one or not—see 66-tree -c.

The field Contains gives you a list of all services enabled in the tree.

You can display the contents list as a graph and only these fields using the command 66-intree -o contains -g boot:

For each service the first field found between '()' parentheses is the corresponding pid of the service, the second one is the state of the service, and next to it is the type of the service, separated by commas, and finally the name of the service is displayed after the parenthesis ')'.

By default the dependency graph is rendered in the order of execution. In this example the 'classic' tty12 is the first executed service and 'bundle' All is the last before it finishes. You can reverse the rendered order with the -r option.

You can display the name and current field and only these fields for each tree using the command 66-intree -o name,current:

    Name        : boot
    Current     : no

    Name        : docker
    Current     : no

    Name        : root
    Current     : no

    Name        : test
    Current     : yes

    Name        : user
    Current     : no
