I'm not sure about the new policy with the cron packages; in any case, the file /etc/crontab is installed both by baselayout (1.7.8-r1) and vcron package, which should probably not be the case. ;^)
Hiya Az: we need to remove this from baselayout if it hasn't been already
Yep yep, checkout gentoo-src. It will be MIA with next baselayout release :)
Should there be any files in /etc/cron.daily,weekly, etc? I have none.
Nope, only some packages adds files there (like sysklogd). Anyhow, closing this bug as it is fixed.
