From 471550c28cb425c15f8f5fa61fdeb885f479e2ae Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ludovic=20Court=C3=A8s?= Date: Thu, 25 Jun 2020 17:36:03 +0200 Subject: channels: Save and interpret 'introduction' field in provenance data. With this change, profiles created by 'guix pull' & co. include channel introductions as part of the channel metadata of each manifest entry. * guix/channels.scm (channel-instances->manifest)[instance->entry]: Add 'introduction' field when CHANNEL has an introduction.

Use it to initialize the 'introduction' field. --- guix/channels.scm | 36 +++++++++++++++++++++++++++++++----- 1 file changed, 31 insertions(+), 5 deletions(-) (limited to 'guix/channels.scm') diff --git a/guix/channels.scm b/guix/channels.scm index 922c99a967..32ada7bbc6 100644 --- a/guix/channels.scm +++ b/guix/channels.scm @@ -851,8 +851,9 @@ derivation."
