How do I know if I'm using devfs or not?
 
I'm reading this [ http://www.pseudorandom.co.uk/2004/debian/alsa/ ] and at one place in it it says

Code:
options snd major=116 cards_limit=4 device_mode=0660 device_gid=29 device_uid=0
# or if you use devfs (gid=29 is 'audio' on Debian)
# options snd major=116 cards_limit=4 device_mode=0660 device_gid=29 device_uid=0
So what is devfs? How do I know if I am using it or not?

Well the full answer to your first question is here: http://www.atnf.csiro.au/~rgooch/linux/docs/devfs.html

But I guess that just raises the question of what was in /dev before devfs came along and that is answered here:
http://www.linux.com/guides/sag/x533.shtml

But to answer your second question simply type 'mount' and look if there is a line saying:

none on /dev type devfs (rw)

or similar - if so you are using devfs.
