Derivation "ATerm" file format - Lix Reference Manual

# Derivation "ATerm" file format

For historical reasons, derivations are stored on-disk in ATerm format.

Derivations are serialised in one of the following formats:

-     Derive(...)

  For all stable derivations.

-     DrvWithVersion(<version-string>, ...)

  The only `version-string`s that are in use today are for experimental features:

  - `"xp-dyn-drv"` for the `dynamic-derivations` experimental feature.
