| Description |
Implementation of command-line functions.
This module holds the common command-line related functions for the
binaries, separated into this module since Ganeti.HTools.Utils is
used in many other places and this is more IO oriented.

|
| Synopsis |
|
|
|
|
| Constants
|
|
| defaultLuxiSocket :: FilePath | Source |
|
The default value for the luxi socket.
This is re-exported from the Ganeti.Constants module.
