# firecrackerconfig(1)

setup the /dev/firecracker symbolic link

## NAME

firecrackerconfig - setup the /dev/firecracker symbolic link

## SYNOPSIS

**firecrackerconfig** *\[ --no-ask \]*

## DESCRIPTION

This man page documents the simple **firecrackerconfig** shellscript.  It is used during the  *configure* phase of  **wmx10**'s postinst script to query and set the */dev/firecracker* symlink that wmx10 uses.

A user invoking this will just type **firecrackerconfig**. It will ask what serial port */dev/firecracker* should be symlinked to.   If a user already has the symlink, the current  *[readlink(2)](/readlink/2.md)* value is used if it looks valid.  All the serial cards with drivers in Linux 2.0.36 are considered valid.  If the user doesn't have the symlink,  */dev/ttyS1* is used as a default.

- **--no-ask**

  **wmx10**'s postinst script calls **firecrackerconfig** with *--no-ask* so as to not pester the user during install if the symlink already exists.  Presumably, if the user is calling this script interactively, they want to be questioned and therefore shouldn't need this option.
