I have migrated from a OSX based system to a linux/debian system. I have all my main org files in a directory ~/org and in OSX this was a symbolic link to ~/a-hard-disk/org (it may have been an alias, ot sure). In Ubuntu, however, I have lots of trouble with org-attach: I attach a file using say copy and when I call C-c C-a o there are no attachments. Sometimes it works but next time I open the file there are no attachments. I experienced similar issues with links:

[[file:./img/myimage.png]] 

was not found but a qualified path worked.

Could this be because of the symlink to my org directory? Is there a better way to do it?

Best,

Henrik
