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
