image: create symlinks needed for merged /usr
Prepare the symlinks required for merged /usr at the time of rootfs creation. The links created in rootfs are: /bin --> /usr/sbin /sbin --> /usr/sbin /lib --> /usr/lib /lib64 --> /usr/lib64 We cannot make these symlinks as part of 'base-files' or some other package. Because at rootfs creation, installation of the package(say kernel) that depends on these root folders/links fails, if package manager installs this package prior to base-files. These symbolic links in top level folder should be present as long as - kernel tools use /lib/{module,firmware} - shell scripts uses "#!/bin/sh" (From OE-Core rev: 3f978f24ae2cf831bd2b82270f6353edda6364a5) Signed-off-by: Amarnath Valluri <amarnath.valluri@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
