The $HOME folder of the br-user inside the container is currently read-write for the br-user. However, practically speaking, it is only read-write when the UID of the user running the container from the host machine is 1000, equal to the UID of the br-user inside the container. For any other UID on the host machine, the $HOME folder is in fact already read-only. Because we do not expect Buildroot to write into $HOME, and in order to have a consistent behavior regardless of the UID of the user on the host machine, we change our Docker image to make the $HOME folder of the br-user entirely non-writable.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at https://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
