module: assemble

|
short_description: Assembles a configuration file from fragments
|
|
description:
|
|
- Assembles a configuration file from fragments. Often a particular
|
|
program will take a single configuration file and does not support a
|
|
C(conf.d) style structure where it is easy to build up the configuration
|
|
from multiple sources. Assemble will take a directory of files that have
|
|
already been transferred to the system, and concatenate them together to
|
|
produce a destination file. Files are assembled in string sorting order.
|
|
Puppet calls this idea I(fragments).

backup:
|
|
description:
|
|
- Create a backup file (if C(yes)), including the timestamp information so

you can get the original file back if you somehow clobbered it

incorrectly.
