Pass the recommended argument in the CPIO manual to make cpio archives reproducible. Reference: https://www.gnu.org/software/cpio/manual/cpio.html#Copy_002dpass-mode Pre-patch diffoscope output: https://gitlab.com/snippets/1874745 Post-patch: https://gitlab.com/snippets/1874746 We can see that post-patch, the archive related differences are removed. The differences are arising from utils/bin/getconf. This will have to be investigated further. However, that is unrelated to cpio.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
