sh: can't access tty; job control turned off

[williamsg]

Hi all, I have a Lab with Yellow Dog installed on every PS3. (I was put in charge but I am new to this)

Recently, I'm getting this error message when I boot up the PS3:

sh: can't access tty; job control turned off

everyone knows what's that means?

Is this is a network problem? shouldn't I'll be getting the error message : "tftp : timeout"?

Please help...
