I found this file tonight:/etc/cron.daily/apt.cron#!/bin/sh[ ! -f /var/lock/subsys/apt ] && exit 0[ -f /etc/sysconfig/apt ] && . /etc/sysconfig/apt[ $CHECK_ONLY == yes ] && OPTS=$OPTS --check-onlyOPTS=$OPTS $EXTRA_OPTIONSexport HOME=/rootif /usr/bin/apt-get -qq update; then    /usr/bin/apt-get dist-upgrade -qq --check-only    if [ $? -eq 100 ]; then        /usr/bin/apt-get -q -y $OPTS dist-upgrade    fifiQuestions:What's the deal, how did it get there?What does it do?
Why is there an apt-get script set in my cron.daily, I'm on Fedora 20?
fedora;apt;cron;yum
Try this:rpm -qf /etc/cron.daily/apt.cronThat's the rpm command which tells you which package a file comes from (if any). In this case, the file comes from the apt package, which you have installed on your system for some reason. This is the apt-rpm port, which, as the name implies, can handle Fedora's RPM packages. It's kind of interesting as a curiosity, but for most practical purposes, you really want yum or the newer dnf.The script does what it says, basically: runs apt-get dist-upgrade daily, with quiet output and no prompts, and the options from /etc/sysconfig/apt if it exists.
