Yes, as pointed out on IRC by zlin, this does not fix the problem at
all (and make it a little worse!). 

Making it conditional on ROOT != / is a good workaround in the
meantime: not breaking anything in all cases, and as  the problem only
appears if a different nxserver was installed before, it still works in
most cases. Thanks!
