Re: missing /dev/tty0

[Yoann A. <ya...@av...>]

You should something like that at the output of
$ ls -l /dev/tty?
crw--w----  1 root root 4, 0 2005-03-19 20:36 /dev/tty0
crw-rw----  1 root tty  4, 1 2005-10-24 18:24 /dev/tty1
crw-rw----  1 root tty  4, 2 2005-10-24 18:24 /dev/tty2
...
$

You wrote about  virtual consoles: in this case you should have 
CONFIG_VT=y in .config file.
Or at least you should something like this at the output of 

$ grep CONFIG_SERIAL_CONSOLE /where-your-kernel-sources-are/.config
CONFIG_SERIAL_CONSOLE=y
$

But be aware of:
  "If you don't have a VGA card installed and you say Y here, the
   kernel will automatically use the first serial line, /dev/ttyS0, as
   system console."

This is from HELP command in menuconfig...

I'll hope this will help...
