With a considerable delay, Sony is inviting users from Spain, Italy and Netherlands, to beta-test new official Android M firmware.

Direct link to Beta: https://play.google.com/store/apps/details?id=com.sonymobile.xperiabeta.signup
I think we are all looking forward to see it in action, and from the beginning, one of the most important question:
Will this firmware be using Verfied Boot (aka. dm-verity) to protect the system?
because if yes, it will render the system unrootable on Locked Bootloader...
So guys and girls from ES, IT and NL ... go on, write your thoughts....
UPDATE 12. March 2016
INSTALLING
You can decide if you want to "install" original unmodified firmware by flashing zip file in recovery or restoring backup of Android M. In any way you need to be on pre-rooted latest Lollipop (v .264) before flashing. Reflash stock if you are on custom ROM. The reason is that this firmware needs bootloader and baseband from v.264 to work.
So to use backup of original Android M Beta:

To flash zip:
There is flashable firmware available thanks to @masuods70 at http://forum.xda-developers.com/showpost.php?p=65871019&postcount=440
For D6633 dual
Users of DualSIM D6633 can flash patch: http://forum.xda-developers.com/showpost.php?p=65877968&postcount=459
ROOTING
This ROM is can be currently rooted with /system R/W access on both LB/UB - need to root in recovery after flashing the system
To root both firmwares you need to stay in the recovery after flash/restore and flash SuperSU, byeselinux and RICdefeat.
There is no prerooted zip available at the moment.
THERE is NO RECOVERY for locked bootloaders.
There is dedicated ROOTING thread by bro @wolbreak
The first good news is that dm-verity is DISABLED on this Beta Marshmallow and it means that the firmware can be rooted. As @Black_Eyes found, rooting can be done with KingRoot v.4.82. However, the root is only partial, because it doesn't disable RIC service which is preventing writes to /system (thanks to @lee480 @shoey63 @EricCartmanez )
I am sure this is excellent news as surely guys are now working on RIC part of the deal.
This news also means, that it can probably be pre-rooted as soon as FTF will be available.
