[%CFEngine_function_prototype(text)%]
Description: Convert an arbitrary string text into a unique legal class name.
This function turns arbitrary text into class data, appending the
SHA-1 hash for uniqueness. It is exactly equivalent to
concat(canonify($(string)), "_", hash($(string),"sha1"); for a given
$(string) but is much more convenient to write and remember.
A common use case is when you need unique array keys for each file in
a list, but files in the list may have the same name when
canonify-ed.
[%CFEngine_function_attributes(text)%]
Example:
commands:
"/var/cfengine/bin/$(component)"
if => canonifyuniquely("start_$(component)");
