Re: Strange boot folder transformation in ubuntu 18.10!?

In hindsight we can now interpret feelslikeautumn's statement, but without the context of what we were discussing - namely partition 1 being mounted to /boot/firmware - his isolated statement did not make any sense. And it doesn't seem like you know for sure why /boot and /boot/firmware has stuff in...

Re: Strange boot folder transformation in ubuntu 18.10!?

When I mount partition 2 as the root filesystem it already has a /boot/firmware folder, so why would the firmware/bootloader, i.e. partition 1 then get mounted there? Do you understand how Linux mounts work? Devices/partitions are mounted onto directories, the root file system has a directory /boot...

Re: Strange boot folder transformation in ubuntu 18.10!?

No offense, but if you think the entire Linux community uses technical wording that you cannot understand, why exactly are you using Ubuntu Server which is not a beginner's Linux distro? I didn't say it was due to technical wording, but due to communication problems. There is only one boot partitio...

I'm referring to doing this on existing installations where the kernel is already installed and not in the live-build script.
Is the kernel actually "installed" or is it just read into memory from the IMG file placed on partition 1 - not to mention the copying of modules and DTBs?

Re: Strange boot folder transformation in ubuntu 18.10!?

Personally I prefer referring to partition 1 as the firmware partition or system-boot partition. Boot partition is a raspbian thing and just adds to the confusion that we've already seen here. All the distros I've seen have a boot partition in the general sense - not exclusive to Raspberry or ARM L...

Re: Strange boot folder transformation in ubuntu 18.10!?

Ubuntu images built using live-build use linux-raspi2 and flash-kernel. linux-raspi2 is an Ubuntu-style kernel with patches from the Raspbian kernel source so that it works better on the Raspberry Pi. The generic kernel can also be used with u-boot and GRUB2 although this kernel includes few optimi...

Re: Strange boot folder transformation in ubuntu 18.10!?

feelslikeautumn, but the whole reason this topic exists is that there are two separate boot folders under partition 1 and partition 2, respectively. If you mount them both to /mnt/piboot and /mnt/piroot you will see. This is the case for Ubuntu RPi3 preinstalled. Partition 2 is usually EXT4 and Part...

Re: Strange boot folder transformation in ubuntu 18.10!?

/boot is used to store the various kernels. It is not used directly by the pi firmware if that is what you mean. It would be used if you had grub2 installed (note typically a pi kernel is missing the necessary module (efi stub) to allow grub2 booting). Are you saying that Kernels are stored under b...

Not at all. A directory can have different contents depending if/how it is mounted. That is what your thread is about.
OK, so does that filesystem partition 2 boot folder (including the firmware subfolder) do anything since the real kernel is meant to reside in boot partition 1?

Re: Strange boot folder transformation in ubuntu 18.10!?

This is a contradiction: The GPU firmware partition is mounted at /boot/firmware.

Due to how the raspi3 images were built there are files in /boot/firmwar...
