Key names should be relative to parent Key name

Issue

There is a different behaviour of various plugins whether their name is absolute or relative, including: 1.) mounting the same file somewhere else does not work 2.) importing somewhere else (than from where it was exported) does not work (See here)

Constraints

• at least the dump plugin must be able to handle its old files

Assumptions

• it will be still easy to support a workflow that exports/imports everything
• mounting across namespaces (user/system) does not make sense

Considered Alternatives

• allow relative/absolute plugins and mark them what they are, tools (e.g. import/export) use this knowledge and react accordingly. This would still not solve issue 1.)

Decision

Key names shall be relative to parent Key name

Argument

Provides a better import/export/remount and also a more uniform experience between different plugins

Implications

Plugins must be adapted to be relative as tracked here.
