This command displays information about trees.
66-intree [ -h ] [ -v verbosity ] [ -l live ] [ -c ] [ -o name,init,enabled,... ] [ -g ] [ -d depth ] [ -r ] tree
(!) If tree is not specified 66-intree will display information about all available trees for the current owner of the process.
The command 66-intree boot as root user on the Obarun 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 give you the name of the tree.
The field Initialized tells if the
The field Enabled reveals the state of the tree—see 66-tree -E.
The field Current tells if the tree is the current one or not—see 66-tree -c.
The field Contains give you a list of all services enabled in the tree.
You can display the contain list as a graph and only these fields using the command 66-intree -o contains -g boot:

For each service the first number found between '()' bracket is the corresponding pid of the service, the second one is the state of the service, the type of the service is shown next to it. Finally the name of the service is displayed.
By default the dependency graph is rendered in order of execution. In this example the 'classic' tty12 is the first executed service and 'bundle' All is the last finished. 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
