mount_kernfs
MOUNT_KERNFS(8) BSD 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_kernfs command attaches an instance of the kernel parameter namespace to the global filesystem namespace. The conventional mount
point is /kern. The directory specified by mount_point is converted to an absolute path before use. 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-independent 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 separated string of options. See the mount(8) man page for possible options
and their meanings.
FILES
boottime the time at which the system was last booted (decimal ASCII).
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.
hz the frequency of the system clock (decimal ASCII).
ipsecsa the directory that contains IPsec security associations (SA) in PF_KEY format. Filenames are SPI in decimal number. The content
of files can be inspected by using setkey(8).
ipsecsp the directory that contains IPsec security policies in PF_KEY format. Filenames are security policy ID in decimal number. The
content of files can be inspected by using setkey(8).
loadavg the 1, 5 and 15 minute load average in kernel fixed-point format. The final integer is the fix-point scaling factor. All numbers
are in decimal ASCII.
msgbuf the kernel message buffer, also read by syslogd(8), through the log device, and by dmesg(8).
pagesize the machine pagesize (decimal ASCII).
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.
version the kernel version string. The head line for /etc/motd can be generated by running: ``sed 1q /kern/version''
SEE ALSO
mount(2), unmount(2), ipsec(4), fstab(5), dmesg(8), mount(8), setkey(8), syslogd(8)
HISTORY
The mount_kernfs utility first appeared in 4.4BSD.
