not necessarily. i like static linking, but sabotage linux links only 
core components statically, because it just makes no sense for 
full-blown desktop apps with dozens of dependencies, you'll end up with 
huge binaries, and some stuff simply can't be linked statically due to 
"modular" plugin design.

indeed. the easy solution is to make /usr a symlink to / , as sabotage 
linux does it. that way you have everything in one path, but available 
in 2 different prefixes. saves a lot of nerves.
