.Sh NAME
|

.Nm kernfs
|
||||
.Nd kernel file system
|
||||
.Sh SYNOPSIS
|
||||
.Bd -literal
|
||||
kern /kern kernfs rw 0 0
|
||||
.Ed
|
||||
.Sh DESCRIPTION
|
||||
The kernel file system, or
|
||||
.Nm ,
|
||||
provides access to information on the currently running kernel.
|
||||
It is normally mounted on
|
||||
.Pa /kern .
|
||||
The file system includes several regular files which can be
|
||||
read, and some of which can also be written.
|
||||
The contents of the files are in a machine-independent format,
|
||||
either a string or an integer in decimal ASCII. A trailing
|
||||
newline character is added when a number is returned.
|
||||
.Pp
|
||||
The mount point contains the following files:
|
||||
.Bl -tag -width copyright
|
||||
.It Pa bootfile
|
||||
The path from which the current kernel was booted.
|
||||
.It Pa boottime
|
||||
The time at which the system was last booted (decimal ASCII).
|
||||
.It Pa copyright
|
||||
The kernel copyright message.
|
||||
.It Pa hostname
|
||||
The current hostname, with a trailing newline. The
|
||||
current hostname can be changed by writing to this file.
|
||||
A trailing newline will be stripped from the hostname being
|
||||
written.
|
||||
.It Pa hz
|
||||
The frequency of the system clock (decimal ASCII).
|
||||
.It Pa loadavg
|
||||
The 1, 5 and 15 minute load averages in kernel fixed-point
|
||||
format. The final integer is the fix-point scaling factor.
|
||||
All numbers are in decimal ASCII.
|
||||
.It Pa pagesize
|
||||
The machine pagesize (decimal ASCII).
|
||||
.It Pa physmem
|
||||
The number of pages of physical memory in the machine (decimal ASCII).
|
||||
.It Pa root
|
||||
The system root directory. In a chroot'ed environment,
|
||||
.Xr mount_kernfs 8
|
||||
can be used to create a new
|
||||
.Pa /kern
|
||||
mount point.
|
||||
.Pa /kern/root
|
||||
will then refer to the system global root, not the current
|
||||
process root. Not currently enabled.
|
||||
.It Pa rootdev
|
||||
The root device. Not currently enabled.
|
||||
.It Pa rrootdev
|
||||
The raw root device. Not currently enabled.
|
||||
.It Pa time
|
||||
The second and microsecond values of the system clock (decimal ASCII).
|
||||
.It Pa version
|
||||
The kernel version string. The head line for
|
||||
.Pa /etc/motd
|
||||
can be generated by running
|
||||
.Dq Ic "sed 1q /kern/version"
|
||||
