I am in a similar boat as you. My 4.4 is setup and working great. One of these days I will update to 4.4.2 through a rooted SafeStrap install. However, I don't have enough benefit at the moment to do so and risk loosing root, etc.
To disable the damn annoying update prompt I have frozen FOTA and MotorolaOTA using TitaniumBackup.
Other unrelated apps frozen is AT&T Locker, Motorola Migrate, myAT&T, Visual Voicemail.
