The mount point does not need to be set into stone so everybody *must* 
use it. I, as Fedora packager, just need some default place where to 
mount it, so applications which need to create/manage groups work 
without any (potentially dumb) user assistance. Of course, advanced 
admin can change the settings and move the groups anywhere, applications 
still need to parse /proc/mounts or use appropriate library like libcgroup.
