My advise is to stack only two. Something like this: losetup -e AES256 -H random /dev/loop7 "$TMPDEV" losetup -e AES256 -H random /dev/loop6 "$SWAPDEV" losetup -e twofish256 -H random /dev/loop5 /dev/loop7 losetup -e twofish256 -H random /dev/loop4 /dev/loop6 If do decide to use $halfsize, then you need to make sure that sizelimit (-s) and offset (-o) options given to losetup must be multiples of 512 bytes. Just cutting some device size in half does not guarantee that. -- Jari Ruusu 1024R/3A220F51 5B 4B F9 BB D3 3F 52 E9 DB 1D EB E3 24 0E A9 DD - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
