# This script handles adding custom apt repositories into
|
|
# /etc/apt/sources.list.d/ files. It bundles the GPG keys which are
|
|
# used to verify the repositories (via `apt-key`), to explicitly pin
|
|
# the trusted signing keys, as opposed to blindly trusting HTTPS.
|
|
#
|
|
# Each /etc/apt/soruces.list.d/foo.list file is created via `--list
|
|
# foo`, where `foo` defaults to `zulip`. The default `zulip.list` is
|
|
# installed in `scripts/lib/install` / `tools/lib/provision.py`, and
|
|
# other `.list` files may be installed by Puppet.
