# Before updating the pinned hash:
|
||
|
|
#
|
||
|
|
# - Push new commits to monero-project/guix from upstream. Do not forget to update
|
||
|
|
# the keyring branch as well. Guix uses this branch to authenticate commits.
|
||
|
|
#
|
||
|
|
# The repository is set to monero-project/guix because fetching from the official
|
||
|
|
# repo at https://git.savannah.gnu.org/git/guix.git is unreliable in CI jobs.
|
||
|
|
#
|
||
|
|
# Do not attempt to push custom changes to monero-project/guix, it will not work!
|
||
|
|
# If a change is necessary to Guix, submit a patch to https://issues.guix.gnu.org/
|
||
|
|
# New packages can be defined in manifest.scm until they are available upstream.
|
||
|
|
#
|
||
|
|
# - Make sure a bootstrapped build works with the new commit using a fresh Guix install:
|
||
|
|
# $ export ADDITIONAL_GUIX_COMMON_FLAGS='--no-substitutes'
|
||
|
|
#
|
||
|
|
# - Check how the update affects our build graph and which packages have been updated.
