persist.img is "persist" which contains data which shouldn't be changed after the device shipped, for example: calibration data of chips(wifi, bt, camera, etc.), certificates and other security related files. For sure even it's "persist" you still can replace it via fastboot, or change things if the devices is rooted, take it for your own risks
It's part of the Android build along with system.img, userdata.img, tombstones.img, recovery.img, etc.
You would alter it if you wanted to modify the build.

It is still not clear to me. I mean like boot.img contains ramdisk and kernel. In similar way what exactly is inside persist.img and what is its use? Commented Sep 4, 2012 at 4:39
