Thanks for your reply. This seems an obscure problem to have immediately after upgrading the system. I've looked at / using fstat and haven't found anything incriminating, but maybe fstat has the same difficulties du has (a small test suggests it doesn't, but who knows?). The real question is: how do I fix / so I can update packages (short of installing a fresh 7.7)?
