* Added a global configuration file (/nix/etc/nix/nix.conf). It

contains options for the garbage collector right now, but other
  stuff can be added here later.

### Option `gc-keep-outputs'
#
# If `true', the garbage collector will keep the outputs of
# non-garbage derivations. If `false' (default), outputs will be
# deleted unless they are GC roots themselves (or reachable from other
# roots).
#
# In general, outputs must be registered as roots separately.
# However, even if the output of a derivation is registered as a root,
# the collector will still delete store paths that are used only a
# build time (e.g., the C compiler, or source tarballs downloaded from
# the network). To prevent it from doing so, set this option to
# `true'.
gc-keep-outputs = false
### Option `gc-keep-derivations'
#
# If `true' (default), the garbage collector will keep the derivations
# from which non-garbage store paths were built. If `false', they
# will be deleted unless explicitly registered as a root (or reachable
# from other roots).
#
# Keeping derivation around is useful for querying and traceability
# (e.g., it allows you to ask with what dependencies or options a
# store path was built), so by default this option is on. Turn it off
# to safe a bit of disk space (or a lot if `gc-keep-outputs' is also
# turned on).
gc-keep-derivations = true
