Kernel and ramdisk patches
Anyone care to share what is patched?
yup
ramdisk:
asr - patch out rootfs SHA1 check
restored_external - patch wiping routine
kernel:
haven't looked into this, but there are four patches, at least some of them are for codesign and apparently one of them has to do with virtual memory mapping.
Thanks
Do you know how the new codesign is added yet? I notice you think they didn't use ldid. It seems that the second patches to asr and restored are codesign (from what I can tell when 2.1 and 2.2 files are compared), but I don't see any in the kernel, they're all simple.
