On an up to date Fedora 26, attempting a mock build targeting EPEL 5, specifically "-r epel-5-x86_64" (on Fedora x86_64) fails thusly:

Well /etc/mock/site-defaults.cfg says this (wrongly I believe):

# By default Mock use simple chroot(1). When you set this to True
# it will use systemd-nspawn(1)
# config_opts['use_nspawn'] = True 

It appears the default was changed at some point but site-defaults.cfg verbiage never updated.

It should probably be updated in mock but you can change the default in /etc/mock/epel-5-{i386,x86_64}.cfg

Thanks,
