Directed Acyclic graph (considering the links too)

In Unix at least, links can make cycles.

Also you say 'DAG' but, that technically could mean multi-rooted. AFAIK Unix systems are singly-rooted; everything, mounted or otherwise, is somewhere below '/'. I suppose Windows might be considered multi-rooted (fully 'DAG'), with a 'root' per drive.

How is it acyclic if you have links?

It is acyclic because, link points to some file but the file does not have a path to that link. if an operating system offers that then when a link is opened it will go into infinite recursion!
