System profile versioning: System profile definition

## 2. System profile definition

Here is how to define a version.

## 2.1 A name

Each system profile version has a name which is used to select it. The name does not contain any spaces.

## 2.2 A title

You can give a title to make menus easier to read.

## 2.3 Default archiving family

Any sub-system without an archiving family will be archived using this one. Most of the time, system profile versions are archived in one or two different families. This avoids repeating the archiving family over and over.

## 2.4 Archiving families

A system profile version is defined by telling Linuxconf how or where the various sub-systems composing it are archived. Sub-system configuration files are archived in a family together.

If two system profile versions are defined so they archive one given sub-system in the same family, then the configuration files for this sub-system will be shared between the two versions. This means that a change done while a given system profile version is active will be available when you switch to the other system profile. Switching between the two versions won't affect the state of this specific sub-system.

A family is just a single word. It can be any word. It becomes a subdirectory in /etc/linuxconf/archive. In this subdirectory, you will find archived copies of the various configuration files saved there. Inside the family directory, you will find a directory hierarchy that duplicates the various directories normally found in a Linux system, such as /etc and /etc/ppp.

Several sub-systems may be archived in the same family.
