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 thedynamic-derivations
experimental feature.
