## Project Description

This project contains the Ruby scripts/classes that are used to control the Hanlon Microkernel (and that interact with the Hanlon server) along with a set of scripts and files that are needed during the Microkernel boot and initialization proces. The files contained in this project are all bundled into the current version of the Hanlon Microkernel (v0.9.0.1). There are three primary services that are included in this project that are started up during the Microkernel boot process. Those services include:

This project contains the Ruby scripts/classes that are used to control the Hanlon Microkernel (and that interact with the Hanlon server). There are two primary services that are included in this project that are started up during the Microkernel boot process. Those services include:

1. The **Hanlon Microkernel Controller**, which is actually contained in the hnl_mk_control_server.rb file (which is, in turn, started up and controlled using the "Ruby Daemons" interface defined in the hnl_mk_controller.rb file)
1919
1. The **Hanlon Microkernel Web Server**, which can be found in the hnl_mk_web_server.rb file and which is used (by the Hanlon Microkernel Controller) to save configuration changes from the Hanlon Server to the 'local filesystem' (remember, everything is in memory). During this process of saving the configuration changes, the Microkernel Web Server will actually restart the Hanlon Microkernel instance (in order to force it to pick up the newly saved Microkernel configuration).

1. The **Local TCE Mirror**, which is actually contained in the hnl_mk_tce_mirror.rb file and which is used to install a few extensions during the post-boot configuration process.

If the Hanlon Microkernel that is being built/used is a development kernel, a fifth service will also be started during the boot process (the **OpenSSH server daemon**). That service is not started in a production system in order to prevent unauthorized access to the underlying hardware through the Hanlon Microkernel (in fact, the openssh.tcz extension is not even installed on these production systems).
21+
In addition, this project also includes a number of additional ruby files and configuration files that are used by these services, and the 'hnl_mk_init.rb' script itself (which is used to start the appropriate Ruby-based services during the Microkernel boot process).

In addition, this project also includes a number of additional ruby files and configuration files that are used by these services, a list of gems that are installed dynamically each time that the Microkernel boots (under the opt/gems directory), a copy of the 'bootsync.sh' script (under the opt directory in this project), and the 'hnl_mk_init.rb' script itself (which is used by that bootsync.sh script to start the appropriate Ruby-based services during the Microkernel boot process).

Copies of the ruby scripts that appear at the top-level of this project's directory structure can be found in the /usr/local/bin directory of the Microkernel. In addition, the files that appear in the hanlon_microkernel subdirectory of this project are all part of the HanlonMicrokernel module, and those files are placed in the /usr/local/lib/ruby/2.0.0 directory in the Microkernel ISO.

It should be noted that this project also includes a set of scripts that are meant to be used to build a new instance of the Microkernel ISO. Instructions for building a new ISO instance using these scripts can be found in this project's Wiki. There are also a number of extensions to the standard Tiny Core Linux ISO that are bundled into the Hanlon Microkernel which are not included in this project. These extensions (and the other dependencies that are needed within the Hanlon Microkernel ISO that are not part of this project) are all downloaded dynamically when the Microkernel ISO is being built. Once again, instructions for building your own (custom) Microkernel ISO can be found in the project's Wiki.

It should be noted that this project also includes a a Dockerfile that is used to build a new instance of the Microkernel container. Instructions for building your own (custom) Microkernel container can be found in the project's Wiki.
