Greetings,

Is there a way to encrypt the swap, var, temp, and home partitions
during install. I've done this with Mandrake, but don't really want to
use mandrake...

Possibly. You'll need to mount them manually, and you may well need to make
your own bootdisk. Build a kernel with cryptoloop support (I presume that's
what you're using) on another system or your system running mandrake, and
make a bootdisk from it. Try and fit everything into one <1.4mb kernel, you
should be able to do it if you only include drivers for your hardware, and
if necessary make non-essential things (sound, usb, anything you won't be
using during install) as modules to install later. Write this kernel and
the install.1 and install.2 images from /rootdisks on the slackware cd onto
floppies. Boot from the kernel disk (with the cd in the drive) and insert
install.1 and install.2 when prompted. Go through the installer
partitioning and setup, but then quit, and remount your hierarchy
under /mnt as encrypted filesystems. (back up anything on them first). Then
restore the contents and edit /mnt/etc/fstab to use encryption. Then resume
the install where you left off, it should all work. Say to use your current
kernel, and install the modules by hand if you have any to install. Once
you've booted your new system you may have to rebuild alsa. Good luck.

Greetings,

Thanks for the reply. Doesn't look to complex to do. I was thinking of
using LoopAES, as I have used it in Mandrake. I'll go check out cryptoloop
when I get a chance. Any idea how cryptoloop is speedwise? I took quite a
speed hit with LoopAES on Mandrake.

Thanks, Rush

I think the speed hit will be similar. Cryptoloop has more algorithms and is
forward-compatiable with dm-crypt, but is less mature than loop-aes, so
loop-aes is probably better in the short term. Just patch the kernel you're
building with loop-aes support.
