Summary
The docker-image is failing to build in GHA:
https://github.com/jetify-com/devbox/actions/runs/16204700194/job/47358742840
The error indicates that the seccomp (secure computing mode) BPF (Berkeley Packet Filter) program that Nix tries to load is incompatible with the Docker container environment on ARM64.
When filter-syscalls = true (the default), Nix uses seccomp BPF to filter system calls for security sandboxing. Setting filter-syscalls = false disables Nix's syscall filtering, which bypasses the seccomp BPF program entirely and prevents the error.
This PR uses the approach from #1811 to fix this for arm64 platforms.
How was it tested?
docker build --platform linux/arm64 -t devbox-image-arm64 -f /Users/savil/code/jetpack/devbox/internal/devbox/generate/tmpl/DevboxImageDockerfile .docker build --platform linux/arm64 -t devbox-image-arm64 -f /Users/savil/code/jetpack/devbox/internal/devbox/generate/tmpl/DevboxImageDockerfileRootUser .BEFORE: these failed with the error seen in the GHA above
AFTER: build successfully
Also confirmed that --platform linux/amd64 would build successfully
