Subject: [PATCH 1/3] install: Parameterize the profile name for 'populate-single-profile-directory'.

From: Ludovic Courtès <[email-masked]>
Date: Sun, 21 Oct 2018 22:49:41 +0200

* gnu/build/install.scm (populate-single-profile-directory): Add
 #:profile-name.  Replace hard-coded occurrences of "guix-profile" with
PROFILE-NAME.  Make the symlink part under /root a function of
PROFILE-NAME.
