Its a good start, but I think, more than just installing a Linux box doesnt help u much @ first.
But dont get disheartened. There are loads of areas where u can develop for linux. Be it App Development,Databases,Embedded Systems , Java, J2EE etc, the list goes on…. .
To start off you can get a head start by learning shell scripting and command line stuff in linux.
Next if u like designing and developing web apps , then learn apache , php with mysql .
If u r a serious into device drivers and other technical stuff , then embedded sys is the way 2 go.
Hope this helps
All the Best in your Endeavours
