Linux pitfall of soft links ln - Rhythm Box - Music Player on Ubuntu
I came across a strange issue on one of my Ubuntu computers. I had added some more MP3 files to my music folder and so I refreshed them by performing an import of that directory in Rhythm Box. The import command will only add new files that are not already added.
To my surprise I ended up with two of each file in my library on Rhythm Box. After a lot of head scratching and thinking that it was a bug in the system I finally found the problem.
The reason for this is that the system I was running this on was a dual boot Windows / Linux computer. Although I hardly use Windows due to the lack of support for other operating system file systems the music files are all on my Windows NTFS partition.
