Linux file system guru Hans Reiser has managed to hit #2 on Google Trends ranking of internet searches at the time of this writing. This is apparently due to coverage of his wife's murder and his subsequent conviction being aired on American TV tonight.
When I first began to dabble with Linux, ReiserFS was one of the up and coming file systems available. It was touted as being superior to ext2 and was even the default file system on an install of SuSE 9.3 (it may have been their earlier, but that's when I started using SuSE).
Since Reiser's arrest, his Linux file system has fallen into oblivion. It's even been dubbed MurderFS by some. Did Hans Reiser inadvertently kill his ReiserFS when he murdered his wife Nina? Although development on ReiserFS successor, Reiser4, continues, Reiser's file system may be breathing its last breath.
