deleting old kernel trees
my /usr/src directory has become quite messy so i want to delete all the old trees, but i am not sure whether it is safe to do so...
is it safe to delete kernel-source-trees from the /usr/src directory where the kernels built from them are still in use?
i imagine it would be, but i really don't want to find out that it isn't after the fact.
thanks in advance for any help on this.
