I'm copy/linking files and have found that a certain file really does not like to be hard linked.
Both gcp -alp Get_started_with_GoPro.url test (gnu-cp) and ln Get_started_with_GoPro.url test fail with Operation not permitted.
Other files link fine, and cp Get_started_with_GoPro.url test1; ln test1 test2 works just fine as well.
How can I find out what is preventing Get_started_with_GoPro.url file from being hard linked?
(I've also verified that other files with same permissions can hard link)
