Combine geli with the md device: dd if=/dev/zero of=/tmp/secret bs=1 count=0 seek=1G mdconfig -a -t vnode -f /tmp/secret -u 1984 geli load geli init /dev/md1984 && geli attach /dev/md1984 newfs /dev/md1984.eli mkdir /mnt/secret && mount /dev/md1984.eli /mnt/secret echo "the formula for Coke is..." > /mnt/secret/secret_formula.txt umount /mnt/secret geli detach /dev/md1984.eli mdconfig -d -u 1984 cp /tmp/secret /mnt/usbdrive (I don't know off-hand the 'cp' options for copying sparse files correctly). Read the man pages for all of the commands you are unfamiliar with. geli(8) has a lot of flexible options. -- Geoff _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
