# NAME

`ccd.conf` — concatenated disk driver configuration file

# SYNOPSIS

`ccd.conf` |

# DESCRIPTION

The `ccd.conf` file defines the configuration of concatenated disk devices, or ccds. It is used by ccdconfig(8) when invoked with the `-C` option and at system boot time. For more information about the concatenated disk driver, see ccd(4).

Each line of the configuration file contains arguments as per the `-c` argument to ccdconfig(8):

ccd ileave [flags] dev [...]

ccd
  The name of the ccd.
ileave
  The interleave, expressed in units of `DEV_BSIZE`. For serial concatenation, specify ‘`0`’.
flags
  The flags for the device, which may be represented as a decimal number, a hexadecimal number, a comma-separated list of strings, or the word “none”.
dev [...]
  The component partitions to be concatenated, which should be of type `FS_CCD`.

A ‘#’ is a comment, and everything to end of line is ignored. A ‘\’ at the end of a line indicates that the next line should be concatenated with the current. A ‘\’ preceding any character (other than the end of line) prevents that character's special meaning from taking effect.
