From e00ade3fb81f89cd7c030f998ccd3e07ef2628f0 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Sat, 28 Apr 2018 22:20:36 +0200 Subject: profiles: Optionally use relative file names for symlink targets. * guix/build/union.scm (symlink-relative): New procedure. * guix/build/profiles.scm: Re-export it. (build-profile): Add #:symlink and pass it to 'union-build'. * guix/profiles.scm (profile-derivation): Add #:relative-symlinks?.
