s6-rc

• s6-rc-compile works in chroot
• For native builds, database is compiled instead of being copied from git repo
• s6-rc-compile must be run natively on the host as it embeds build-time paths into the compiled service database (the database itself is architecture‑independent); a workaround exists if both installation paths on the host and target match then we can compile the db on the host and copy it to the target (future versions of s6-rc will add runtime options to override these paths, making things relatively easier)
• There is no test suite
