MOUNT_KERNFS(8)         OpenBSD System Manager's Manual        MOUNT_KERNFS(8)

NAME
     mount_kernfs - mount the /kern file system



SYNOPSIS
     mount_kernfs [-o options] /kern mount_point

DESCRIPTION
     The mount_kern command attaches an instance of the kernel parameter
     namespace to the global filesystem namespace.  The conventional mount
     point is /kern. This command is normally executed by mount(8) at boot
     time.

     The filesystem includes several regular files which can be read, some of
     which can also be written.  The contents of the files is in a machine-in-
     dependent format, either a string, or an integer in decimal ASCII.  Where
     numbers are returned, a trailing newline character is also added.

     The options are as follows:

     -o      Options are specified with a -o flag followed by a comma separat-
             ed string of options.  See the mount(8) man page for possible op-
             tions and their meanings.

FILES
     boottime   the time at which the system was last booted (decimal ASCII).
     byteorder  the _BYTE_ORDER for this kernel.
     copyright  kernel copyright message.
     hostname   the hostname, with a trailing newline.  The hostname can be
                changed by writing to this file.  A trailing newline will be
                stripped from the hostname being written.
     domainname
                the domainname, with a trailing newline, behaves like a host-
                name.
     hz         the frequency of the system clock (decimal ASCII).
     loadavg    the 1, 5 and 15 minute load average in kernel fixed-point for-
                mat.  The final integer is the fix-point scaling factor.  All
                numbers are in decimal ASCII.
     machine    the architecture this kernel compiled for.
     model      the model of the processor this machine running on.
     msgbuf     the kernel message buffer, also read by syslogd(8),  through
                the log device, and by dmesg(8).
     ncpu       the number of CPUs in this machine.
     ostype     the OS type for this kernel ("OpenBSD").
     osrelease  the release number of the OS.
     osrev      the revision number of the OS (BSD from <sys/param.h>).
     pagesize   the machine pagesize (decimal ASCII).
     posix      the _POSIX_VERSION for this kernel.
     physmem    the number of pages of physical memory in the machine (decimal
                ASCII).
     rootdev    the root device.
     rrootdev   the raw root device.
     time       the second and microsecond value of the system clock.  Both
                numbers are in decimal ASCII.
     usermem    the number of pages of physical memory available for user pro-
                cesses.
     version    the kernel version string.  The head line for /etc/motd can be
                generated by running: ``sed 1q /kern/version''
