Re: [9fans] Is /proc an Plan9 invention ?

[Rob Pike]

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.

http://en.wikipedia.org/wiki/Procfs:


 UNIX 8th Edition

Tom J. Killian 
 
implemented the UNIX 8th Edition 
 version of |/proc|: he 
presented a paper titled "Processes as Files" at USENIX 
 in June 1984. The design of procfs 
aimed to replace the /ptrace 
/ 
system call used for process tracing.

the english wikipedia page on Plan9 implies that procfs was
an Plan9 invention. 


Is this true ?
