What are the advantages compared > to btrfs ? reiser4 was denied for 'layer violation'. btrfs violates those layers even more. I do no know btrfs. But there are two nice things about reiser4: it takes your data seriously. It tries everything to make sure your data hit the platter. Device does not support barriers? Reiser4 detects that and goes into sync mode. Second, reiser4 is really, really really fast (except mounting).
