.TH pmon\-UPDATE 8 2017\-10\-18 1.00 "pmon configuration tool"
.SH NAME
pmon\-update \- program to generate pmon menu files
.SH SYNOPSIS
\fBpmon\-update\fR
.SH DESCRIPTION
pmon\-update is a tool used to generate the menu files used by the pmon bootloader. Options can be configured in /etc/default/pmon-update.
.SH OPTIONS
.IP "PMON_UPDATE=""\fBtrue\fR|false""" 4
Specifies whether pmon-update is allowed to update the PMON boot.cfg. Setting this to "true" means pmon-update may update the PMON boot.cfg when invoked. Default is "true".
.IP "PMON_ALTERNATIVES=""\fBdefault recovery\fR""" 4
Specifies available alternative boot modes. "default" is used for normal boot and "recovery" is used for rescuing or troubleshooting boot-up issues. Default is "default recovery".
.IP "PMON_BOOTDEV=""\fB(wd0,0)\fR""" 4
Specifies the default boot device. (wd0,0) is the first partition in the first SATA/ATA storage device; (nvme0,0) is the first partition in the first NVMe storage device; (usb0,0) is the first partition in the first USB storage device. Default is "(wd0,0)".
.IP "PMON_DEFAULT=""\fB0\fR""" 4
Specifies the default boot entry. Setting to "0" means PMON will boot into the first entry recorded in the configuration file. Default is "0".
.IP "PMON_ENTRIES=""\fBall\fR""" 4
Specifies how many boot entries to list in boot.cfg. "all" means pmon-update will list all kernel versions found. Setting this variable to "2" means pmon-update will only enumerate up to two kernel versions. Default is "all".
.IP "PMON_MENU_LABEL=""\fBLinux\fR""" 4
Specifies the text used as description in the PMON boot menu. Value is an arbitrary string. Defaults to "Linux".
.IP "PMON_PARAMETERS=""\fBro quiet\fR""" 4
Specifies the default kernel parameters to append to each boot entry. Default is "ro quiet". With "recovery" entries, the "quiet" parameter will be automatically omitted.
.IP "PMON_ROOT=""\fBroot\fR=\fIDEVICE\fR""" 4
Specifies the root partition. This value is automatically detected by invoking findmnt(8) - a utility provided by util-linux, or alternatively, by parsing /etc/fstab in the current system root. Uncomment this if you would like to use a custom root device.
.IP "PMON_TIMEOUT=""\fB50\fR""" 4
Specifies the default menu timeout (in seconds), or the time before PMON automatically boots the default entry without user input. Default is "5".
