Re: help in sysfs

[glauber@mpcnet.com.br]

It was mounted, as told me by mount(1)

but, I think it was a problem in the order of the mounts
maybe it was mounted over the old /dev
I mounted it again, and it worked fine. (at least, the pts
others things remais)
But, this brings me another doubt (an extension to the first
one):
Why there is not any information about the pts in /sys ?
There is only a directory entry called
/sys/cdev/tty/pts
May I conclude that there is no info avaiable about chardevs?

One more to go:
I use PPPoE to connect to the net. When I loaded the modules,
some entries apeared somewhere in /sys/udev, but the /dev
entry was not created, and I had to mknod it
Does anyone knows why ?

I may be (very) wrong, but it seems to be a behaviour common
to chardevs
