bcfg2-admin init won't overwrite /etc/bcfg2.conf

[lueningh]

If /etc/bcfg2.conf already exists, it refuses to overwrite the file with the options you give it. Here's a patch to give people the option:

This patch won't work if the bcfg2.conf file doesn't already exist, as 'result' will be undefined.
