From c73a8ea2718b597dfbb8948deb8d14a0d74c4d8f Mon Sep 17 00:00:00 2001 From: Midnight Magic Date: Thu, 17 Sep 2015 14:17:26 -0700 Subject: [PATCH] Clarifying offline build process using gbuild --url and noting it is not done automatically. At some point along the line, fully offline builds were no longer happening when strictly following the release-process.md instructions. We should ensure that users who might want to torify or build offline need to take extra steps to remain offline. Also, corrections to build process: including gverify examples for new builders. --- doc/gitian-building.md | 60 +++++++++++++++++++++++++++++++++--- doc/release-process.md | 69 +++++++++++++++++++++++++++++++----------- 2 files changed, 107 insertions(+), 22 deletions(-) diff --git a/doc/gitian-building.md b/doc/gitian-building.md index 169727adc..b434ae8a5 100644 --- a/doc/gitian-building.md +++ b/doc/gitian-building.md @@ -330,10 +330,11 @@ There will be a lot of warnings printed during the build of the image.
