 Hi there,
 
 I wasn't able to replicate the error you encountered using dump.  One
 thing I did notice is that the man page for restore indicates that the
 -x flags will restore owner, modification time and mode 'if possible'.
 
 That said, according to the restore man page, the -r flag was
 speficially intended to be used to restore and rebuild a file system
 that has been created with newfs, thus making it a more favourable
 choice over the -x flag.
 
 Assuming this is correct, I've included a minor patch for the FAQ to
 correct this.
 
 Cheers,
 Marc
