I have installed BackTrack 3 yesterday on my USB flash disc, and I can say it's working great!
New things are:
- there is no installer
- Snort - Auto installs, has snortsam patches, can act as an IDS.
- Karma-msf scripts - evilap.sh
- Compiz in USB release
- Several featured tools by SV - spoonwep, ezpwn, etc.
- VMware Edition installed originally on VMware Server 1.0.6 - VMWare tools installed
- Orinoco drivers excluded
- Broadcom cards inject well now
- etc...
I will play with it in the next several days...
