Nitpicking: What happens if the disk decides to relocate a close to failing sector containing mlocked data during resume zeroing? This just means that there will be sensitive data around on the disk that can't be zeroed out anymore but which might be recovered by specialized companies/institutions. Encrypting these data in the first place reduces this problem to a single potentially problematic sector. If this risk is then still too high for you then there's always the possiblity to use a sledgehammer :-) -- Andreas Steinmetz SPAMmers use [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
