# Runc-dmz

runc-dmz is a small and very simple binary used to execute the container's entrypoint.

## Making it small

To make it small we use the Linux kernel's [nolibc include files][nolibc-upstream], so we don't use the libc.

A full `cp` of it is here in `nolibc/`, but removing the Makefile that is GPL. DO NOT FORGET to
remove the GPL code if updating the nolibc/ directory.

The current version in that folder is from Linux 6.6-rc3 tag (556fb7131e03b0283672fb40f6dc2d151752aaa7).

It also support all the architectures we support in runc.

If the GOARCH we use for compiling doesn't support nolibc, it fallbacks to using the C stdlib.
