Which shell do you use? Does this fail if you use bash or only if the
Busybox sh is involved. That quoting trouble looks like a problem in
Busybox sh when using single quotes. This fails on other programs to as
the backslash quoting character is/is not removed by the shell
argument passing as expected. So try this first before digging to deep
into sed.
