NAME
pbl - manage boot loader confguration.
SYNOPSIS
pbl [OPTIONS] IMAGE
DESCRIPTION
pbl is a light wrapper to unify some common boot loader configuration
tasks.
It is not intended to provide a comprehensive API to boot loader
configuration.
Most notably, not all options make sense for all boot loaders.
Supported boot loaders have a sub directory in /usr/lib/bootloader
containing a shell script for each option. To add support for a new
boot loader create a new directoy with its name and add scripts for
options you need.
OPTIONS
--install
Install (or update) boot loader.
Note that this does not update the boot loader configuration.
--config
Create (or update) boot loader configuration.
--show
Print current boot loader.
--loader _BOOTLOADER
Set current boot loader to BOOTLOADER.
Note that this only changes a config variable. To actually use the
new boot loader, run pbl --install and pbl --config.
--default ENTRY
Set default boot entry to ENTRY.
--add-option OPTION
Add OPTION to default boot options (grub2).
--del-option OPTION
Delete OPTION from default boot options (grub2).
--get-option OPTION
Get OPTION from default boot options (grub2).
--add-kernel VERSION [KERNEL [INITRD]]
Add kernel with version VERSION. Optionally pass kernel and initrd
explicitly (systemd-boot).
--remove-kernel VERSION [KERNEL [INITRD]]
Remove kernel with version VERSION. Optionally pass kernel and
initrd explicitly (systemd-boot).
--default-settings
Print default kernel, initrd, and boot options.
--log LOGFILE
Log messages to LOGFILE (default: /var/log/pbl.log).
--version
Show pbl version.
--help
Write this help text.
FILES
/etc/sysconfig/bootloader
General boot loader related configuration settings.
/var/log/pbl.log
Default log file.
/usr/etc/logrotate.d/pbl
Logrotate rules for /var/log/pbl.log.
/usr/lib/bootloader
Directory with specific config scripts for each supported boot
loader.
