bootcd2disk - copy a system running from bootcd to a disk
SYNOPSIS
bootcd2disk [-i|-s|-m] [-d debug_runtime_config] -- [-h|--help]
[-c|--conf CONF] [-y|--yes] [-url url] [--only_mount] [--only_unmount] [--only_copydata]
[--only_sync] [-p|--only_print_options]] [-o|--use_originaldiskname] [-z|--zerodsk]
[--variable_from_bootcd2disk.conf(5) value] [--function_from_bootcd2disk.conf(5) definition]
DESCRIPTION
bootcd2disk is used to write a running system to disk. It was originally used do write a running bootcd
built with bootcdwrite to disk, but it is also possible to write a system directly to an attached disk.
The system can be copied to one or more disk partitions seen by the running system. When running from
bootcd, it is possible to let bootcd2disk automatically find a disk, make partitions on it, copy the cd
to the disk and make the disk bootable.
OPTIONS
-i|-s|-m|-d debug_runtime_config
Run bootcdwrite in interactive, silent, minimal control or debug mode. See shellia(1) for this
standard shellia options.
-c|--conf CONF
use the bootcdwrite config options from file CONF. Default:
CONF=/etc/bootcd/bootcd2disk.conf
-h|--help
print help and exit
-o|--use_originaldiskname
if bootcd2disk.conf was created by bootcdmk2diskconf, not only the variable DISK0 is defined as auto
but also ORIG_DISK0 is defined with the original device. To use it this option exists.
-y|--yes
answer always yes
-url url
If bootcd2disk is slow on your system (because of a slow CD/DVD drive or the HP ILO virtual CD
interface), you can use an image server to get the bootcd iso image from. The swap partition of the
installed system will be used as temporary space for the iso image.
The image server url is configured with this option. Example:
bootcd2disk -url http://192.168.1.1/cdimage.iso
Another way the increase the performance is the use of the mounted CD/DVD itself for the copy.
Example:
bootcd2disk -url file:///dev/sdc0
The swap partition of the upcoming system must have enough space to get the whole image!
--only_mount
After bootcd2disk did partition, format and install the disk, the disks can be mounted again with this
option. For example to run update-grub in chroot on the mounted disk:
# remount disks to /mnt/bootcd.disc/ bootcd2disk --only_mount
# prepare chroot mount --bind /dev /mnt/bootcd.disc/dev mount -t proc none /mnt/bootcd.disc/proc
mount -t sysfs none /mnt/bootcd.disc/sys mount -t devpts none /mnt/bootcd.disc/dev/pts
# run update-grub in chroot chroot /mnt/bootcd.disc update-grub
--only_unmount
If the disks are mounted with option --only_mount , they can be unmounted with this option.
--only_copydata
This will not create partitions, but only copy data to the directory COPYDEST defined with --COPYDEST
COPYDEST. Filesystems have to be mounted before. The Bootloader will not be activated.
-p|--only_print_options
Print the options calculated from defaults, config-file and commandline and exit.
Hint: This option may display more information about defined functions in a non-bash environment, if
calling bash bootcd2disk -p ....
-z|--zerodsk
This option writes zeros to the beginning of a disk before using it.
--variable_from_bootcd2disk.conf(5) value
variables listed in bootcd2disk.conf(5) can be overwritten from command line. For example a variable
called VARIABLE will get the value VALUE with the option: --VARIABLE VALUE
--function_from_bootcd2disk.conf(5) definition
functions listed in bootcd2disk.conf(5) can be overwritten from command line. For example a function
fun() { echo "hello world"; } could be defined with the option: --fun 'fun() { echo "hello world"; }'
--only_sync
To use this option, bootcd2disk should have been run before, because the target disk should be
partitioned and formatted already. With ---only_sync only the steps needed to sync will be done.
That means the target disc will be mounted, the files will be synced, the bootloader will be activated
and the target disk will be unmounted.
ENV
All variables, that can be given as OPTIONS or in the bootcd2disk.conf file, will not be taken form
Environment variables.
Only the following variables will be set as Environment variables.
LUKS_PASSWD
This variable contains the luks passphrase. It is used to initialize luks partitions and to open luks
partitions. If this variable is not set in the envrionment it will be asked interactively by
bootcd2disk if needed.
