9. The build chain and cloonix-patchelf

rootfs_targz_store.sh          mmdebstrap into a tree, then a curated copy into the delivery;
                               compiles copy_libs from build_tools/toolbox/fill_common.c inside
                               the chroot, hence gcc and libc6-dev in the list
copy_libs                      ldd every executable of bin, sbin, the plug-in directories, and
                               each sub-directory named in create_libs_txt; copies the libraries
build_cloonfs                  checks the tools, compiles everything
pack_cloonfs                   copies each binary in, runs copy_libs, runs patchelf, installs
                               the demos, makes the certificate, keeps make_cloonix_cert in bin
create_toy_targz.sh            the rootless tarball from an installed bundle: the crun that
                               wraps cloonix, the init starter, the <net>cmd script

a package taken out of LIST whose files a copy list names    the copy fails
a file taken out whose path another script rewrites          a sed fails
a library no longer harvested, its binary in a directory     nothing fails at build;
copy_libs does not scan                                      the binary does not start on the target

for f in cloonfs/bin/*; do ldd $f | grep "not found"; done
