* Global configuration option `env-keep-derivations' to store pointer
to derivations in user environments. Nice for developers (since it prevents build-time-only dependencies from being GC'ed, in conjunction with `gc-keep-outputs'). Turned off by default.

### Option `env-keep-derivations'
|
||||||
|
#
|
||||||
|
# If `false' (default), derivations are not stored in Nix user
|
||||||
|
# environments. That is, the derivation any build-time-only
|
||||||
|
# dependencies may be garbage-collected.
|
||||||
|
#
|
||||||
|
# If `true', when you add a Nix derivation to a user environment, the
|
||||||
|
# path of the derivation is stored in the user environment. Thus, the
|
||||||
|
# derivation will not be garbage-collected until the user environment
|
||||||
|
# generation is deleted (`nix-env --delete-generations'). To prevent
|
||||||
|
# build-time-only dependencies from being collected, you should also
|
||||||
|
# turn on `gc-keep-outputs'.
|
||||||
|
#
|
||||||
|
# The difference between this option and `gc-keep-derivations' is that
|
||||||
|
# this one is `sticky': it applies to any user environment created
|
||||||
|
# while this option was enabled, while `gc-keep-derivations' only
|
||||||
|
# applies at the moment the garbage collector is run.
