Hi folks,
the english wikipedia page on Plan9 implies that procfs was
an Plan9 invention.
Is this true ?

http://en.wikipedia.org/wiki/Procfs:
UNIX 8th Edition
Tom J. Killian
<http://en.wikipedia.org/w/index.php?title=Tom_J._Killian&action=edit&redlink=1>
implemented the UNIX 8th Edition
<http://en.wikipedia.org/wiki/Version_8_Unix> version of |/proc|: he
presented a paper titled "Processes as Files" at USENIX
<http://en.wikipedia.org/wiki/USENIX> in June 1984. The design of procfs
aimed to replace the /ptrace
<http://en.wikipedia.org/w/index.php?title=Ptrace&action=edit&redlink=1>/
system call used for process tracing.

I'm pretty sure Peter Weinberger (pjw) did the very first, which
Killian adapted and improved when pjw lost interest.
The big change in Plan 9 was moving to a true file system hierarchy
instead of just one file and a pile of ioctls. Linux's /proc is very
close in overall design.
