Everything is plain for squashfs/aufs. BTW, a plain kernel for Android doesn't exist! Android needs a bunch of patches, some of their effects might be unpredictable from my experience. I would recommend that you try first with another OS, aka a plain and really standard Linux to figure out if it's not Android that is causing some problems,
