I have set up many laptops and netbooks with linux and have always used either full-disk encryption or ~/ encrypted. Its really easy to do and ANY laptop/netbook/tablet/pad/whatever_next mobile device should be encrypted. I won’t get into the mechanics of why, just do it. The last article I wrote about this is no longer online (Maysville Linux Users Group, circa 2007) and it was much harder to accomplish back then, often requiring custom kernels to be compiled, etc. Backtrack has “nearly” everything it takes right on the live cd.
- A laptop
- bootable media (backtrack on usb stick, cdrom, some other distro, etc)
- Internet connection (backtracks only requirement is to download two files)
