gen_init_cpio: remove leading `/' from file names
When we extracted the generated cpio archive using "cpio -id" command, it complained, cpio: Removing leading `/' from member names var/run cpio: Removing leading `/' from member names var/lib cpio: Removing leading `/' from member names var/lib/misc It is worse with the latest "cpio" or "pax", which tries to overwrite the host file system with the leading '/'. So the leading '/' of file names should be removed. This is consistent with the initramfs come with major distributions such as Fedora or Debian, etc. Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Acked-by: Mike Frysinger<vapier@gentoo.org> Signed-off-by: Michal Marek <mmarek@suse.cz>
