[Tails-testers] Tails 3.0-beta4 feedback

1) On a kaby lake m3-7y30 tablet (cube mix plus, teclast X5), bluetooth is not working (3 year old debian 8.2 on 3.16.xxx kernel picks up bluetooth easily) - lsmod shows hid0 and lot of related kernel modules that I dont understand; in the UI the Bluetooth slide button gets into the activated state but I can not list / pair with my bluetooth mouse and keyboard (settings -> bluetooth panel is always empty, re-opening again shows the bluetooth is turned off)

2) on restart with persistent storage unlocked, settings do not seem to be activated from previous reboot (keyBoard rate stays slow and second monitor is not mirrored)

3) please include having /proc/config in the kernel so that I could dump it and rebuild the same kernel on the other machine :)

4) thank you for 4.9 kernel !! iwl-xxxx.22 finally enables wifi on kaby lake; I even made my debian turn on wifi with this firmware you included; and I wont install tails 2.12 because iwlfifi.ko doesnt work for kernels < 4.2

5) 3.0-beta4 seems to boot faster than 3.0-beta3, thank you!!

6) it would be cool if users knew how to do post - release adjustments; of course it's easy for a linux guy (mount squashfs, copy into another partition, drop a bluetooth driver kernel module, create the new squashfs bundle and replace on the usb key), but requires some digging and investment of time for a non-experienced user; probably publishing the release script / build tools / "buildroot" configs would help us moving the tails distribution forward together, or implement individual post-release patches
