After reboot what would happen to fcsk? Hi Iantcho , I dont know for a fact the effect with a power outage, but I use it quite a lot on laptops (which a) freeze sometimes out of nowhere , and b) sometimes dont resume properly,). In both situations, I've usually had geli mounted disks (1 x 6 GB, 1 x 500 MB) running when the events happened. ( as well as a 4 GB swap which is also GELI backed) They (touch wood) haven't suffered data loss. /usr and /var seem be more affected by this ungraceful shutdowns than the .eli devices. I suppose it's all cool thanks to soft-updates, and the fact that GELI encrypts on a per block basis (yeah, no more pgp-busted disks like in Windows :) ). good luck, Beto
