What is 66?

Sixty-six is a collection of system tools built around s6 and s6-rc created to make the implementation and manipulation of service files on your machine easier. It is meant to be a toolbox for the declaration, implementation and administration of services where seperate programs can be joined to achieve powerful functionality with small amounts of code.

Examples of what can be achieved by assembling different programs provided by 66:

• Frontend service files declaration.

• Easy creation of a scandir.

• Nested supervision tree.
• Instance service file creation.
• Multiple directories service file declaration(packager,sysadmin,user).
• Easy change of service configuration.
• Automatic logger creation.
• Service Notification.
• Organizes services as a tree.
• Easy view of service status.
• User service declaration.
• Automatic dependencies service chain.
• ...

Note: This documentation tries to be complete and self-contained. However, if you have never heard of s6 and/or s6-rc you might be confused at first. Please refer to the skarnet documentation if in doubt.

Why is 66 necessary?

Implementation and handling of service files based on s6 and s6-rc can be complex and difficult to understand. This led to the creation of the 66 tools. Why the name

66 is the result of the combination of the former s6 and s6-rc. It is a lot faster and easier to write and remember when writing. Apart from that it is a nice command prefix to have. It identifies the origin of the software and it's short.

Expect more use of the 66- prefix in future obarun.org software releases and please avoid using it for your own projects.
