It is occasionally necessary for nix-on-droid to change
|
|
configuration defaults in a way that is incompatible with
|
|
stateful data. This could, for example, include switching the
|
|
default data format or location of a file.

The <emphasis>state version</emphasis> indicates which default
|
|
settings are in effect and will therefore help avoid breaking
|
|
program configurations. Switching to a higher state version
|
|
typically requires performing some manual steps, such as data
|
|
conversion or moving files.
