$ sudo dpkg -i ~/src/{spl,zfs}/*.deb

That should take care of both the SPL and ZFS packages.

If you’re interested in hand ciphers, have you seen Bruce Schneier’s Solitaire? It’s the only one I’ve ever heard of that has some actual cryptographic strength behind it; great way to pass the time with a deck of cards if you don’t want to actually play solitaire.

Last time I needed them was to use this ancient (circa 1990) laptop that ran OS/2. Only input/output it supported that I could marginally use was floppy; had to dig up a still-ancient-but-less-so machine from the basement which had both floppies and a working Ethernet port, then run the copy from there. I don’t think I could even do that now; the computer with the requisite drive is long gone.

A note: if you’ve got a recent Emacs, then you don’t have to bother with saving, shredding, etc.; simply find the new file passwords.gpg, type in its contents, and save, and Emacs will automatically encrypt it without ever writing plaintext to disk.

Then if you mount your image with losetup /dev/loop0 my-image.img will have the partitions exposed in /dev/loop0p1 and /dev/loop0p2

I always add a file with the options under /etc/modprobe.d/loop.conf so that the extra options are loaded automatically upon boot:

sudo echo “options loop max_part=63 max_loop=8″ > /etc/modprobe.d/loop.conf
