David E. O'Brien 135c56336a Libraries should _never_ call exit() themselves (or its alternate spelling
`err()').  libdisk does! and additionally libdisk gets confused on Alpha
disks with foreign disklabels, throws up its hands and exits.  This is
the cause of the "going no where without my init" install bug on the Alpha.

So now on the Alpha, rather than call err(), we print the error string and
continue processing.
