As explained here.

Here is a screenshot of the new window that pops up when you try to use ADB:

Unfortunately it appears this works only for windows. MAC and Linux just sit there. Nice feature. (Not)

Edit: SDK may not be updating correctly. Grrr

Great work on the OTA link guys
Hopefully this fixes some of the 4.2.1 bugs.

No, on Linux it's working in the same way, probably you need to connect / disconnect the device while adb server is running ... and you need a propper adb executable (1.0.31 or newer should be fine).

Same here, easier than flashing a custom ROM. Working perfect

Got it working on Linux. The key to the secret was that after I got the window to open for the trust verification, I had to reboot the Nexus 7. And then rerun my root tool. On the MAC it still failed to complete the root process. Linux got it, I have TWM and full root.

So in short.

1. Update SDK (from Google not apt)
2. Copy adb into root tool.
3. Connect USB run adb, and agree to trust.
4. Reboot Nexus.
5. Rerun root tool and all is golden.

Did your rootkeeper do it from the first try or did you have to try several times? Did it take long?

Never used that before to be honest.

It worked on the first try (well second, keeping in mind that the first time i forgot to backup root), i just backed up root - flashed - and restored root

Hmmm that's weird indeed, mine didn't work. I'll have to solve it tomorrow, would right but TWRP hid my backup somewhere I can't find and I'm busy doing homework.

Been trying to read up if having SuperSU installed could have caused any problems but nothing comes up saying it would. Maybe I needed to have Superuser instead.

Then again I used root for the Lag Fix app perhaps with this update I won't need it.

We'll see, thanks!

-can't tell if the bluetooth internet connection bug is fixed though, i'll have to check that tomorrow at work.

I flashed the update using the Nexus Root Toolkit
backed up apps and data, backed up root with OTA rootkeeper> launched advanced utilities > flash zip from computer
-there was no need to restore the apps and data after the update since nothing was lost
-restored root and installed custom recovery using GooManager

L.E.: in case you lost root during the update you can use Nexus root toolkit to boot into a custom recovery image and restore a rooted backup of your previous version:
- start Nexus 7 in fastboot mode
- open Nexus root toolkit and launch advanced utilities
- check fastboot - bootloader
- check "boot (temporary)" press boot and select the custom recovery image
- restore the backup then follow the instructions above.

UPDATE: apparently the bluetooth tethering option is still buggy; meaning that i pair the tablet with a 3g connected phone and when i enable the internet access option it gets disabled automatically after a few seconds.
UPDATE 2 - also noticed
- timeleft calculated and displayed for Play Store downloads
- more secured ADB due to the whitelist (?) - judging from what other users posted - i didn't test this yet.

SupeSU shouldn't be the problem since i also had/have it installed before/after the update.
