LINPROCFS(5)		  FreeBSD File Formats Manual		  LINPROCFS(5)

NAME
     linprocfs -- Linux	process	file system

SYNOPSIS
     linproc	     /compat/linux/proc	     linprocfs	     rw	0 0

DESCRIPTION
     The Linux process file system, or linprocfs, emulates a subset of Linux'
     process file system and is	required for the complete operation of some
     Linux binaries.

     The linprocfs provides a two-level	view of	process	space.	At the highest
     level, processes themselves are named, according to their process ids in
     decimal, with no leading zeros.  There is also a special node called self
     which always refers to the	process	making the lookup request.

     Each node is a directory containing several files:

     exe     A reference to the	vnode from which the process text was read.
	     This can be used to gain access to	the process' symbol table, or
	     to	start another copy of the process.

     mem     The complete virtual memory image of the process.	Only those
	     addresses which exist in the process can be accessed.  Reads and
	     writes to this file modify	the process.  Writes to	the text seg-
	     ment remain private to the	process.

     Each node is owned	by the process's user, and belongs to that user's pri-
     mary group, except	for the	mem node, which	belongs	to the kmem group.

FILES
     /compat/linux/proc		      The normal mount point for the
				      linprocfs.
     /compat/linux/proc/cpuinfo	      CPU vendor and model information in
				      human-readable form.
     /compat/linux/proc/meminfo	      System memory information	in human-read-
				      able form.
     /compat/linux/proc/pid	      A	directory containing process informa-
				      tion for process pid.
     /compat/linux/proc/self	      A	directory containing process informa-
				      tion for the current process.
     /compat/linux/proc/self/exe      The executable image for the current
				      process.
     /compat/linux/proc/self/mem      The complete virtual address space of
				      the current process.

EXAMPLES
     To	mount a	linprocfs file system on /compat/linux/proc:

	   mount -t linprocfs linproc /compat/linux/proc
