how are we to handle LE updates once Krypton is released
I will rebuild the addon in next days for all projects. And when addon will not start I will rebuild it again 
where are you adding the above config
/storage/.kodi/userdata/addon_data/http://service.web.lamp/mysqld.cnf
etails about the purpose of xdotool
I was using it with my Opera addon to minimize and maximize windows. And there are plenty of other use cases.
will this stop the audio from first location
Yes.
As a result we support BT audio only as an output device, not to receive.
Is this really true? Few months back it worked both way but maybe then it was removed?
Sems I missed the post here 
To make storage partition ready I made one service which copies files from somewhere under /usr to /storage. When image is build extra files are copied to /usr. It was working fine when I was needing this.
I think you need to look for this option in BIOS?
I can see this being a potential long-term issue
Because imx6 project is community type I see no real problem with this. It will newer be supported in a same way as others. And users must understand that.
If this is a problem then maybe should just be removed?
Order in which patches are applied: LibreELEC.tv/unpack at master · LibreELEC/LibreELEC.tv · GitHub
Thanks malin, I will look it. And checked on v2.1.
But it is not on my priority list.
are you even sure you are using libreelec from USB stick? 
I have only model i4p. Maybe there is a bootloader issues to not booting there (can't check that)?
I'm wondering: why don't you copy KERNEL/SYSTEM files to openelec generated sd card? Then you don't need to use usb stick to boot.
1. I think you should more emphasize the fact, that your fresh green fork comes from the solid root/base work of sraue (and the rest of OE team).
And who was the rest of the OE team by your oppinion? 
Who helped to get solid base.
How can i run the typical "make menuconfig" for the linux kernel while compiling libreelec
cd build.LibreELEC-........./linux-.../
make menuconfig
and then you can compare changes in .config file and projects/.../linux/linux......conf .
This solution is working for years and I would say with confidence that it msut work on kszaq's build too. He would not remove something like that.
Just tested with Kodi Krypton and the path /storage/.kodi/media/Fonts is correct. Just put some ttf file there. After reboot you can select new font for subtitle.
