How to preserve environment variable in chroot

Q: I put

config_opts['environment']['VAR'] = os.environ['VAR']

into config, but the variable is not preserved.

A: Environment is sanitized by consolehelper when elevating UID. You need to alter /etc/security/console.apps/mock too.

I cannot build Fedora package on RHEL/CentOS 7

Q: I am on RHEL 7 and when I run mock -r fedora-28-x86_64 --init I get:

....
---> Package patch.x86_64 0:2.7.6-4.fc28 will be installed
---> Package redhat-rpm-config.noarch 0:108-1.fc28 will be installed
Error: Invalid version flag: if

A: This is not Mock error. This is because redhat-rpm-config in Fedora 28 contains rich dependency: Requires: (annobin if gcc). This is a new rpm's feature and is not recognized by RHEL7's rpm. When you are installing the fedora-28 chroot, mock is using host's rpm. And RHEL7 rpm cannot install this package, because of the new feature, which does not recognize.

The solution is to use mock's bootstrap feature. It is not enabled by default, because there are still some unresolved issues, but generally it works. Try:

mock -r fedora-28-x86_64 --init --bootstrap-chroot
