Moving this back to the haiku-development list, so others can chime in. :-)

The /proc filesystem is a direct reflection of the system kept in
memory and represented in a hierarchal manner. The effort of the /proc
filesystem is to provide an easy way to view kernel and information
about currently running processes. As a result, some commands (ps for
example) read /proc directly to get information about the state of the
system. The premise behind /proc is to provide such information in a
readable manner instead of having to invoke difficult to understand
system calls.
The /proc fs can be used for system related tasks such as:
Viewing Statistical Information
Finding out Hardware Information
Modifying Runtime Parameters
Viewing and Modifying Network and Host Parameters
Memory and Performance Information
I get these information from here
http://linuxgazette.net/issue46/fink.html.
Sorry I'm not familiar with the Haiku os. So I found there is not a
/proc filesystem like other unix-like system. Maybe there is some
mechanism similar to /proc filesystem in Haiku.
We have our own tools and API to get this information (like our own ps,
listarea). I am not sure that there is a high enough need for the /proc
file system on Haiku. I may be the wrong person to judge this, though.
