Re: But wait, theres more... [Fwd: Bug#415123: -R option can't append to a plain file]

[Bill Kendall <wkendall@sgi.com>]

Tim summed it up pretty well. I'd agree it's more of
a feature request. In case it isn't clear, the way
to resume a dump to a regular file is to point xfsdump
at a new file, just like incremental dumps go in a
different file than the base dump.
