I am wondering if I am able to install from standard Ubuntu 9.10 or 10.04 (when released) Repositories on a BackTrack 4 (final) Hard Drive install? I want to use BackTrack4 as my primary OS, but I am guessing I may want some other programs that I use from the Ubuntu Repositories as well. I would like to install them from the Repositories for consistency, if possible. So basically I am asking if I add Ubuntu repositories into BackTrack4, will they work and/or will I run into any major issues? I know its Ubuntu based, but wasn't sure if the kernel was different or other issues which may cause serious issues.

Thanks,
Sparky
