+ Better loopback mounts with NBD —
+ Take your loopback mounts to the next level with nbdkit +

+

+

+ Loopback devices let you turn a raw file into a device. + Loopback mounts let you mount filesystems from a raw file. + Network Block Device with the nbdkit server takes + this concept to the next level, elegantly solving simple problems + like how to mount filesystems from a compressed file, but as we + shall see in this talk offering far, far more ... +
