Not that I know of. The encryption happens before the write, so it won't (shouldn't) cause any extra writes. Be prepared for a performance drop. If you have a CPU with AESNI, it helps. > Should I split /dev/ada1 into two separate partitions, one for real > /usr/local and one for my HOME and only crypt this with geli(8)? Hard to say, but I think that encrypting only the necessary data would be better for netbooks with relatively slow CPUs.
