Nilfs is applicable to / by putting nilfs2.ko in initrd, but I think using nilfs for /home is a convenient choice. > Is there any specific tweak in NILFS2 to use with an SSD?

I'm working on some performance optimization for high speed drives espacially for SSD. Revising GC is another priority, but it would need some time. The massive I/O by the current garbage collector may shorten the life of SSD. So, I don't recommend yet. If you are not interested in snapshots, I think nilfs is not always a good choice because high-end SSD drives are already doing lfs like optimization internally. Intel SSD exactly looks like this sort of drives though I'm using nilfs on X25-M and X25-E ;) > PS: If you would like to answer me with a Cc: to some mailing list > so that others benefit from the information, feel free to do so if > you wish.
