image - /system and /data file system of Android -

-

when build android sources, end 3 images. ramdisk.img, system.img , userdata.img. i'm trying understand these made of , how used android. came across articles "/system" yaffs2 file system. 1) if want make use of on real board, should file system yaffs2 or can any? 2) if want 3 images file system(say ext2), how do that?

you can modify kernel accept filesystem want (ext2 , ext4 2 examples), if can make compile. then, it's matter of mounting , formatting volume corresponding filesystem.

there patches different kernels in github , xda-developers. need browse around find patch particular device. unfortunately not can sole devices single hack.
