Make that option the default when BR2_REPRODUCIBLE is selected in order to avoid problems with timestamps embedded in compiled python files.įs/common.mk 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -git a/fs/common. When BR2_PACKAGE_PYTHON_PY_ONLY is selected. The guide for build + flash SD card for the Raspberry Pi 4 w/ Gentoo is in the Getting Started section of the readme.Boot/syslinux: add an option to install an MBR blob. If configured, the Gentoo setup will happen from-source on the device rather than download a precompiled image: the dockerfile downloads the latest Gentoo stage3 for arm and runs emerge to compile, inheriting the device-specific CPU mtune cflags from the Buildroot build. Some others available: 'core/gentoo', 'core/alpine', 'core/debian', 'core/nixos'.

The 'skiff/core' layer enables Docker ('apps/docker') and a default environment based on Ubuntu with a full graphical desktop environment.

The user environments run in persistent containers, so everything still works exactly as expected - with Gentoo emerge or apt or other distributions (can run multiple in parallel). This makes it impossible to break boot-up via config or package manager mistakes. Some of the advantages of this approach include: a fully up-to-date and optimized read-only host system for networking, kernel, drivers, and security, reproducible behavior across different types of hardware (all versions are pinned), cross-compilation for faster compilation, easier experimentation with custom kernel configs, isolation of workloads with containers. The host OS can be easily remotely updated with the push_image.sh script, using rsync. The default configuration produces a minimal (~100Mb) in-RAM host OS with SSH and network connectivity, and includes a comprehensive set of debug tools. You can then ssh to the 'core' user to enter the Gentoo environment. Layers are merged together as specified in the SKIFF_CONFIG comma-separated environment variable.Īs a basic example: SKIFF_CONFIG=pi/4,core/gentoo starts Gentoo on a Raspberry Pi 4 in a Docker container (with full systemd support). SkiffOS adds a configuration layering system to the Buildroot cross-compiler, which makes it easy to re-target applications to new hardware.
