Subject: board/raspberrypi/post-build.sh: only tweak /etc/inittab if available
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=720b9095a6a9fb23c7a2d7d3e4dabbe6b5299b12;p=buildroot.git

board/raspberrypi/post-build.sh: only tweak /etc/inittab if available

As pointed out in bug #9161, we don't always have an inittab file (if
systemd or no init is used), so the post build script should only try to
tweak it if present.
