Since TLXOS is mainly standard Debian or standard Raspbian, we only provide source for modified debs or unpackaged files here. You can get source code for standard Debian/Raspbian from any Debian/Raspbian mirror site. We realise that this is a mess, but with the exception of closed source components, and kernel source code that is even more untidy, we're not holding out on you - we actually prepare(d) TLXOS releases using what's here. Note that the initramfs used by ThinLinX Firmware Maintenance (TFM) mode is based on the DietPC project rather than Debian. Source code for DietPC is available at dietpc.org. TFM included some proprietary ThinLinX packages (tms_client etc) that are not part of standard DietPC.
