The exec command is not implemend by default for init.rc despite what the readme.txt says. Add the following to get it working.

file: android/system/core/init/builtins.c

int do_exec(int nargs, char **args)
{
    const int cmd_line_max = 256;
    char cmd_line[cmd_line_max];
    int cmd_length, i;
