/etc/mock/defaults.cfg == site-wide default configuration option setup. Set
things like default mock root dir, caching options, etc.

/etc/mock/default.cfg  == default chroot if no '-r' option specified

Yes, these are stupid names, but we are stuck with them for now because
otherwise it breaks people's existing configs, and I dont want to have to listen
to certain people complain...

If you want to run mock without the '-r' option, make a symlink to the config
you want to use.

Per the docs:

$ man mock
... cut ...
       ... cut ...
       The content of a chroot  is  specified  by  the  configuration  specified
 with  the  -r  option.  A  default  configuration  file  is  specified  in
       /etc/mock/default.cfg, which is usually a symlink to one of the installed

... cut ...
       -r CHROOT
              Uses specified chroot configuration as defined in
/etc/mock/<chroot>.cfg If none specified, uses the chroot linked to by

$ head -n 6 etc/defaults.cfg  | tail -n3
# This config file is for site-specific default values that apply across all
# configurations. Options specified in this config file can be overridden in
# the individual mock config files.

2 points:
1) Last times I installed mock it worked out of the box.  Now it doesn't.  
Either I did something wrong here, or something needs some more explanation.

2) This is a .fc8 package, but there is no f8 config.  There are fedora-7 and 
fedora-devel, but not fedora-8.

F8 configs are in updates-testing (mock 0.8.7). Will be in updates next week.

Mock 0.7 had some specfile magic that made symlinks on install, but 1) the spec
was mostly re-written and this feature was dropped.

This also had the effect of silently using the wrong config if user didnt pay
attention. I'd rather let which config is the default be a site-local policy via
admin-created local symlink.
