 +if [ -e /bin/ramfsinit ]; then

better use:
elif [ -e /sbin/ramfsinit ]; then

 +if [ -e /sbin/ramfsinit ]; then
 + exec /sbin/ramfsinit
 +fi

[OpenWrt-Devel] [PATCH] [boot] /init: allow easier customisation of ramfs boot.

[Stephen Parry]

/init is the first pid 1 process in an initramfs environment. This fix adds
lines to check for the existence of /bin/ramfsinit or /sbin/ramfsinit and exec
if present. This allows packages to switch root early in the boot process. This
will help support booting or kexecing from external storage and go some way
toward fixing ticket #17465.
