Revision 11784

Added by Aaron Marcuse-Kubitza about 11 years ago

lib/sh/util.sh: import_vars: don't overwrite vars that are already defined, to allow the caller to specify their own values for the vars to create. this requires callers that rely on the overwriting functionality to reverse the order in which they run use_* commands, so that the higher-precedence use_* is applied first and the other one as the default values for the first.
