mock epel-5 target build fails on Fedora 26

[Sam Varshavchik]

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:

It appears that mock wants to run systemd-nspawn inside the EPEL-5 chroot,  
which is not going to get very far.

Should this work/be supported, on F26? I'm just trying to see if some of my  
stuff still builds on 5.

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,
Richard

--old-chroot CMD line option should help you.
