[GoogleCodeExporter]

What steps will reproduce the problem?
1.r12379,ppc/debug
2.patch conf/mods.config as follow:
$ diff conf/mods.config templates/ppc/debug/mods.config 
24d23
<   include embox.driver.tty.tty
32c31,32
< 

---
>   @Runlevel(3) include embox.init.start_script
>   //include embox.cmd.sh.tish
34,35d33
<   @Runlevel(3) include embox.cmd.sh.tish(prompt="$ ", rich_prompt_support=1, 
builtin_commands="cd export mount")
<   @Runlevel(3) include embox.init.start_script(shell_name="tish", 
tty_dev="ttyS0", input_buffer=80, shell_start=1)
3.run embox

What is the expected output? What do you see instead?
