Currently the default value for mock_build_srpm_cmd is fedpkg --dist f25 srpm.
mock_build_srpm_cmd
fedpkg --dist f25 srpm
The --dist option is deprecated in favor of --release, as far as I know. Also, since all the users currently use MBS to build for Boltron, i.e. F26, and some packages check the Fedora version which they're being built against, this should point to f26 by default, so users don't have to override it in their configuration.
--dist
--release
