I've just thought of a potential problem (or even maybe a benefit in some cases...)
Users can set/unset 'nodump' on files/directories they own. A clueless user could accidentally set all their stuff to 'nodump', and a malicous one could remove a nodump on their home directory and create large junk files. (This assumes that nodump isn't set on any of the parent directories out of the users control) Ok, an extreme case, but worth noting for anyone considering using the 'nodump' method on a multi-user system!
