These are CDlinux' kernel command line parameters. They are all OPTIONAL. In most cases, you can safely ignore them and use the default values.

CDL_AMOUNT

CDlinux can auto detect/mount your disks/partitions (coldplug & hotplug). This feature is enabled in CDlinux standard edition. But for safty, it is disabled in CDlinux_mini by default. For example, if you are running CDlinux_mini to rescue your disk/partition, you surely don't want this feature. But, if you do want it, you can use this parameter.

  default: yes for CDlinux standard
           no  for CDlinux_mini
  example:
      CDL_AMOUNT=yes	# auto detect and mount
      CDL_AMOUNT=no	# don't mount, detect only

CDL_CMD

Things to run before extra packages/modules are installed. Unless you want to run something in the very early init stage, don't use this. In most case you can use the rc.local script instead.

  default: no default
  example:
      # let your first md be /dev/md1 instead of /dev/md0:
      CDL_CMD="mdadm -Ac partitions -m 0 /dev/md1"
      # you can also specify multiple commands:
      CDL_CMD="echo 'Hi!'; echo 'Hi!' | sed 's/!/ again!/'"

CDL_DEV

On which device is CDlinux located?

  default: /dev/sr0
  example:
      CDL_DEV=/dev/hda1
      CDL_DEV=UUID=42656e5a-1971-0825-0001-d5d4d1b1bae9
      CDL_DEV=LABEL=YourDiskLabel
      CDL_DEV=LABEL="Your Disk Label"

CDL_DIR

In which directory (of the CDL_DEV file system) is CDlinux located?

  default: boot/CDlinux, CDlinux
  example:
      CDL_DIR=Some/Dir/CDlinux
      CDL_DIR="Some Dir/CDlinux" # your boot loader should
                                 # support this though

CDL_GUI

Should CDlinux start Graphical User Interface (X Window) automatically?

  default: yes, if X installed and RAM >128M
  example:
      CDL_GUI=yes
      CDL_GUI=no

CDL_LANG

System language/locale.

  default: en_US.UTF-8
  example:
      CDL_LANG=zh_CN.UTF-8

CDL_LOOP

Should CDlinux install all modules in “loop” mode to save RAM?

  default: determined dynamically.
           If you have enough RAM, run in the memory.
           If no enough RAM, fallback to "loop" mode.
  example:
      CDL_LOOP=yes
      CDL_LOOP=no

CDL_WAIT

How many seconds should CDlinux wait for storage devices to get ready?

  default: 8 seconds, if needed.
  example:
      CDL_WAIT=16
