Released on - 2020-07-21.

Mock 2.4 features:

• The file /dev/btrfs-control is now available in chroot if host supports it. This allows to create btrfs-based image builds. [fedora-infra#9138].

• Copy source CA certificates - Prior to this change, we would only copy the “extracted” SSL CA certificates into the chroot. If anything ran “update-ca-trust” inside the chroot, this would delete our custom SSL certificates from the “extracted” directory. For example, Fedora and RHEL’s main “ca-certificates” package always does this in %post, and any custom third-party package could do this as well. Copy the entire parent directory so that “sources” and “extracted” are both present in the chroot. With this change, “update-ca-trust” does not wipe out the CA certificates from the chroot. [#588]

• Add module_setup_commands configuration option, The new config option obsoletes module_enable and module_install configuration options (but those are still supported), and allows users to also configure “disable”, “remove” and other commands.

  Each command can be specified multiple times, and mock respects the order of the commands when executing them.

  Artificial example: (1) Disable any potentially enabled postgresql module stream, (2) enable specific postgresql and ruby module streams, (3) install the development nodejs profile and (4) disable it immediately.

    config_opts['module_setup_commands'] = [
        ('disable', 'postgresql'),
        ('enable',  'postgresql:12, ruby:2.6'),
        ('install', 'nodejs:13/development'),
        ('disable', 'nodejs'),
        ]

Mock 2.4 bugfixes:

• .rpmmacros is now created in “rootdir” instead of “basedir” [rhbz#1848201]
