Otherwise it is shown when compiling, like this: # We use the flags suggested in nolibc/nolibc.h, it makes the binary very small. gcc -fno-asynchronous-unwind-tables -fno-ident -s -Os -nostdlib -lgcc -static -o runc-dmz _dmz.c strip -gs runc-dmz Having it before the target is equally clear and will not be shown while compiling.

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, 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.
