MOUNT_KERNFS(8) BSD System Manager's Manual MOUNT_KERNFS(8) NNAAMMEE mmoouunntt__kkeerrnnffss - mount the /kern file system SSYYNNOOPPSSIISS mmoouunntt__kkeerrnnffss [--FF _f_s_o_p_t_i_o_n_s] _/_k_e_r_n _m_o_u_n_t___p_o_i_n_t DDEESSCCRRIIPPTTIIOONN The mmoouunntt__kkeerrnn command attaches an instance of the kernel parameter namespace to the global filesystem namespace. The conventional mount point is _/_k_e_r_n. 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. FFIILLEESS 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). 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. pagesize the machine pagesize (decimal ASCII). physmem the number of pages of physical memory in the machine (decimal ASCII). root the system root directory. In a chroot'ed environment, mmoouunntt__kkeerrnnffss can be used to create a new _/_k_e_r_n mount point. _/_k_e_r_n_/_r_o_o_t will then refer to the system global root, not the current process root. 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 _/_e_t_c_/_m_o_t_d can be generated by running: ``sseedd 11qq //kkeerrnn//vveerrssiioonn'' SSEEEE AALLSSOO mount(2), unmount(2), fstab(5) CCAAVVEEAATTSS This filesystem may not be NFS-exported.
