lutrainit is an init system for Linux written in Go.

lutrainit will do the following:

  1. Set the hostname
  2. Remount the root filesystem[1]
  3. Mount all other non-network filesystems and activate swap partitions
  4. Start processes with config files in /etc/lutrainit/lutra.d/ after their dependencies ("Needs") are started. See conf/ for a samples config.
  5. Start some TTY or anything other user-specified.
  6. Kill running processes, unmount filesystems, and poweroff the system once that last login session ends.

(The way step 4 is handled isn't very elegant and will likely fail if you have too many slow startup processes.)

You can also create a file /etc/lutrainit/lutra.conf for some basic configuration.

If there are any lines of the form autologin: username it will automatically log in as that username. (If there's multiple autologin directives, it will create the appropriate number of ttys.) If any line contains persist: true, then when a tty exits, it'll respawn the tty instead of powering down the system once all the ttys are gone.

See the conf/ folder for what you can put in /etc/lutrainit/ including services files in /etc/lutrainit/lutra.d/.


A tool exists and communicate with the init daemon using RPC on socket /run/ottersock, it can then show init version, statistics about goroutines, memory, etc.


sudo cp lutrainit/lutrainit /sbin
sudo cp lutractl/lutractl /sbin

then add init=/sbin/lutrainit to your grub configuration. (Or alternatively, make /sbin/init a symlink to lutrainit.)

[1] This shouldn't be required, since mount -a should take care of it in step 3 according to mount(8), but as far as I can tell it doesn't.
