Description Indrek Ardel 2017-11-24 00:39:19 UTC
Created attachment 25822 [details]

I have 3 filesystems, mounted /, /a and /b

If (absolute) symlink /a/file (-> /somefile) is moved using File.Move to /b/otherfile, then instead of relocating the symlink to /b/otherfile (-> /somefile), it copies the /somefile to /b/otherfile and deletes the original symlink /a/file. Expected result would be that the symlink is simply moved/renamed and still points to /somefile.

I am using Ubuntu 17.10 with mono in the repro attached.
