Hello David,
Thanks for the suggestion, I will write to Alan,
I have a suggestion for the troubleshooting section of the porting guide.
Please add information about the kernel's console parameter, similar to the
one in https://wiki.ubuntu.com/Touch/ContainerArchitecture:

> People that are porting their devices to the Ubuntu Touch container model
> should take into account that Ubuntus upstart is used as init system.
> Upstart likes to have an actually existing device as /dev/console. Many
> Android kernels do not provide this as default or even have something like console=none
> or console=ram hardcoded in their boot commandline arguments. Such
> drawbacks in the kernel or commandline need to be fixed to be able to use
> this model properly (here <http://paste.ubuntu.com/5939625/> is for
> example a kernel patch used on the i9100 image to change the behavior of
> CONFIG_CMDLINE_EXTEND ... now using this option appends the kernel cmdline
> to the bootloader one instead of pre-pending, this way console=tty1 can
> be handed over as the last cmdline argument and with CONFIG_VT_CONSOLE
> and CONFIG_HW_CONSOLE set in the kernel config upstart is now happy).

Thank you,
Vladislav
