15.Sh DESCRIPTION
16The Linux process file system, or
17.Nm ,
18emulates a subset of Linux' process file system and is required for
19the complete operation of some Linux binaries.
20.Pp
21The
22.Nm
23provides a two-level view of process space.
24At the highest level, processes themselves are named, according to
25their process ids in decimal, with no leading zeros. There is also a
26special node called
27.Pa self
28which always refers to the process making the lookup request.
29.Pp
30Each node is a directory which contains the following entries:
31.Pp
32Each directory contains several files:
33.Bl -tag -width status
34.It Pa exe
35A reference to the vnode from which the process text was read.
36This can be used to gain access to the process' symbol table,
37or to start another copy of the process.
38.It Pa mem
39The complete virtual memory image of the process.
40Only those addresses which exist in the process can be accessed.
41Reads and writes to this file modify the process.
42Writes to the text segment remain private to the process.
43.El
44.Pp
45Each node is owned by the process's user, and belongs to that user's
46primary group, except for the
47.Pa mem
48node, which belongs to the
49.Li kmem
50group.
