.SH DESCRIPTION
.B Loadmap
updates the kernel loader maps when a new kernel is installed.  The
old map is backed up to \fB/boot/boot.map.old\fP, and a new map
is installed \fB/boot/boot.map\fP.  The boot sector (first sector /
512 bytes on the device) is also written, and backups are kept
\fB/boot/bsect.*\fP.
.SH OPTIONS
.TP
.B \-r, \-\-root ROOT_DIR
Sets the root directory \fBROOT_DIR\fP that \fBloadmap\fP will change to
before accessing any files.  If this option is not specified, then
/ will be used.
.TP
.B \-R, \-\-rdev BOOT_DEV
Sets the boot device \fBBOOT_DEV\fP to write the map onto.  If this option
is not specified, then \fB@DEFBOOT@\fP will be used, or the device specified
in the configuration file, normally \fB@CONFIGFILE@\fP (see \fIboot.conf\fP(5)).
.TP
.B \-C, \-\-config CONFIG
This option specifies an alternate configuration file \fBCONFIG\fP to read
the details out of.  The default file is \fB@CONFIGFILE@\fP.
.TP
.B \-l, \-\-list
This will list out the current contents of the current kernel map files
in a human readable form.
.TP
.B \-v, \-\-verbose
Prints out the entries that are added to the kernel map.
.TP
.B \-h, \-\-help
Prints out a summary of available command line options.
.TP
.B \-V, \-\-version
Prints out the version number and date of compilation of loadmap.

The loader map \fB/boot/boot.map\fP must not be deleted.
