After porting some build scripts into drone I’m facing the problem to build flatpak extensions. It boils down to running the flatpak-builder tool.
flatpak, being a sandbox environment, does some odd things. In the end, it needs a custom seccomp profile. The profile is derived from the default, with two added syscalls: clone and pivot_root.
Is it possible to apply a custom seccomp profile on a docker instance on drone.io somehow?
