Description Ross Burton 2014-11-18 16:12:00 UTC 
mkfs.ext3 takes my machine (3GHz Xeon with SATA disks) 8 minutes to copy a core-image-sato-sdk rootfs (totalling 3GB) into the filesystem image.  During this time CPU usage is high and disk IO is rarely more than 600K/s.

I understand this is an apples-and-oranges thing but cp -a && sync of the same rootfs takes 30 seconds.
