Subject: [PATCH v2 1/4] utils: Add #:base-directory to
 call-with-temporary-directory.
Date: Fri, 19 Apr 2019 15:04:24 +0100

This allows more easily creating temporary directories within a specific
directory. This is motivated by using this in inferior-eval-with-store.

* guix/utils.scm (call-with-temporary-directory): Add optional keyword
argument, base-directory.
