|

# Understanding links:
|
||||
# When populate-volatile is to verify/create a directory or file, it will first
|
||||
# check it's existence. If a link is found to exist in the place of the target,
|
||||
# the path of the target is replaced with the target the link points to.
|
||||
# Thus, if a link is in the place to be verified, the object will be created
|
||||
# in the place the link points to instead.
|
||||
# This explains the order of "link before object" as in the example above, where
|
||||
# a link will be created at /var/test pointing to /tmp/testfile and due to this
|
||||
# link the file defined as /var/test will actually be created as /tmp/testfile.
