Grml

grml is a Debian (originally Knoppix) based GNU/Linux live-CD especially designed for textool users, l33t g33kz and system administrators.

Compressed

The CD is stored in a compressed filesystem which holds about 2.1 GB of software.

TrueCrypt involvement

The grml CD seems to be the only Live-CD which includes Truecrypt. This is a live-CD you may want to have lying around if you are using Truecrypt to store all your subversive files.
