the M(file) module - including M(copy), M(template), and M(assemble).

do not exist. If C(file), the file will NOT be created if it does not

exist, see the M(copy) or M(template) module if you want that behavior.
|
|
If C(link), the symbolic link will be created or changed. If C(absent),

directories will be recursively deleted, and files or symlinks will be

unlinked.

- accepts only C(default) as value. This will restore a file's SELinux context

in the policy. Does nothing if no default value is available.
