# Use rsync over ssh to copy files. This particular invocation of
|
|
|
|
|
# rsync makes a backup of the file before overwriting it. For example,
|
|
|
|
|
# if cdist overwrites /etc/passwd then you'll end up with the old copy
|
|
|
|
|
# at /etc/passwd~cdist.

|

|
# cdist config --remote-copy /path/to/this/script target_host
