How to create an encrypted partition?
I have a little Netbook on which I want to install Ubuntu 10.10 (32-Bit) on. However, since it is a portable PC I want to completely encrypt the file system (in case of theft).
Currently it runs Windows 7 Starter and I use TrueCrypt which installs a custom boot loader that asks for the password. I remember from the past that Linux can do that as well by putting /boot on it's own, unencrypted partition.
Since it's been ages since I last worked with file system encryption (I remember setting up LVM and a custom patched grub to ask for the password) I wonder how that would work nowadays and if there is a step-by-step how-to for it?
