First impressions of mock 1.1.3

[Paul Howarth]

Good:

I no longer need my selinux workaround:

config_opts['files']['selinux/enforce'] = "0"


Bad:

New option max_fs_size for tmpfs plugin doesn't seem to have a default
value; at least I get a traceback if I use my old config, which had
just:

config_opts['plugin_conf']['tmpfs_enable']                      = True
config_opts['plugin_conf']['tmpfs_opts']['required_ram_mb']     = 2048



Root cache is huge because of cache files getting copied to the cache.
The following change restored sanity:

                         )



Mock always exits with non-zero exit code due to problems uumounting 
filesystems, leading my build scripts to declare the builds as duds:

I'll have to get my script to ignore mock's exit status for now
and check for built packages in the result directory I think.
