) Nothing, barring that NFS doesn't start up properly.

) Right. I set inetd to debug, and did an strace -f on it. Look at this:
)
) 16785 getpeername(0, {sin_family=AF_INET, sin_port=htons(1936), sin_addr=inet_addr("127. 0.0.1")}, [16]) = 0
) 16785 setsockopt(0, SOL_SOCKET, SO_KEEPALIVE, [1], 4) = 0
) 16785 open("/dev/ptmx", O_RDWR) = 3
) 16785 ioctl(3, TCGETS, {B38400 opost isig icanon echo ...}) = 0
) 16785 ioctl(3, 0x80045430, 0xbfffd7f8) = 0
) 16785 stat("/dev/pts/0", 0xbfffd780) = -1 ENOENT (No such file or directory)
) 16785 close(3) = 0
) 16785 write(0, "telnetd: All network ports in us"..., 36) = 36
)
) What's up. /dev/pts has no files in it. I thought that when unix98 pty
) support was compiled in, the kernel was supposed to make a pty file there,
) when it was stated or opened...
Is devpts even mounted ?? Does /proc/filesystems list it ??
)
) According to 'ps -ef' all the shells are using ttyp?? files - why not
) ptys?
)
) USB support kicks ass BTW. Kist noticed that it starts off a few kernel
) threads to deal with different things. That's hella cool.
