+ (and /etc/ in case of --volatile=yes). Specifically, this
+ means that operating systems that follow the historic split of /bin/ and
+ /lib/ (and related directories) from /usr/ (i.e. where the
+ former are not symlinks into the latter) are not supported by --volatile=yes as
+ container payload. The option does not require any particular preparations
