From 6a8ef36fe62c1b53572b0cf64685ece6190b22e5 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Mon, 14 Feb 2005 13:07:09 +0000 Subject: * 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').
