Can't create inline file

I’m trying to create the inline file /etc/services in my Neutrino 2.0 build
script. I can’t find out what’s wrong but the file just does not show up in
the target. I could later create it manually when the system is running (by
running “cat > /etc/services”). The following is the relevant lines in my
build script. Any idea?

[type=link] /etc=/dev/shmem

/etc/services = {

tftp 69/udp


/etc/foobar = {

foo bar
