Given that collision resistance isn't at all the concern behind having the embedded md5sum, I'm not sure that it's really a case that we have to switch. Switching to a single SHA-256 would mean that we lose the incremental checking which is actually very useful in the case of the failure mode to speed up failing. I suggested adding a single SHA-256 hash, not removing anything. Or perhaps add a SHA-256 hash, SHA-256 fragment sums, and keep a single MD5 sum to allow mediacheck when booting from an older medium. (But you're right, the justification to add this feature is pretty weak.) We will consider patches sent to anaconda-maint-list, but are unlikely to implement this on our own. Agree with Chris Lumens. If someone will post the patch it can be integrated. Closing. |
