Okay, here's a TL;DR on the Droid lineup root situation. Essentially, you're out of luck at this point. No root for you! (Or for me, or for a lot of other annoyed users out there. You're not alone.)
Let me reiterate: if you currently have a brand new Droid running 4.4, no root is possible at the moment.
That being said, you're probably getting mixed accounts of this because of the following. Droid Maxx/Ultra/Mini sounds a lot like the Moto X--and they're very similar phones. However, the Moto X DOES have root on 4.4. It's a complicated process that involves downgrading to 4.2, installing a backdoor, and upgrading again to 4.4, then using the backdoor to regain root access. However, as the Droid Maxx/Ultra/Mini have locked bootloaders, it is not possible to downgrade after accepting the OTA upgrade to KitKat 4.4, and most new phones in the lineup are being shipped out with 4.4 already installed.
The first inkling of possible root was when noted dev and exploit-master jcase mentioned, tangentially and on twitter, that he HAD found an exploit for our phones. However, the exploit is not suitable for casual user usage, and still doesn't unlock write protection on the phone, making it essentially useless. Oh, and as a result of the locked write protection, root would be lost any time you restarted the phone. Jcase will be revealing the exploit at the blackhat conference this coming August as a teaching tool, but don't expect it to turn into anything we'll be seeing a solution out of.
The next glimmer of hope came a few weeks ago; remember how I said we couldn't downgrade because of our locked bootloaders? Some Motorola employee started selling bootloader unlock codes for the Droid lineup. You could send the guy 40 bucks and your IMEI number and he'd send you back a device-specific code to unlock your bootloader. Which through an even more complicated process, does eventually allow for root. However, as of about 2ish (?) weeks, the guy selling the codes has stopped; it seems like he/she/them/it/whatever no longer has access to the database containing the unlock codes. A few lucky people got codes before that happened--the process seemed sketchy, and those of us like myself who hesitated are now left with locked down phones.
So yeah, at various points, it's been possible to get root--which, when trying to read up on this stuff, makes it a tad hard to follow.
No root now, though, not if you're already on KitKat 4.4.
Sorry for the disappointment. Keep your ear to the ground in case someone offering codes pops up again and is legit--but I wouldn't hope too hard.
