I thought about doing that, but given the low frequency of format
changes decided it could wait until there's more than one old format
to support. -K without an argument could be treated as "generate
the previous media format", or with an argument it could generate
a specific format. I'm okay with requiring a version argument though,
being explicit is better.
FWIW, the way things have always worked is that xfsrestore provides
backwards compatibility for all dump formats. xfsdump has, until
now, always generated the current format. It's nice to provide
the ability to generate old formats during a transition period,
but long-term I don't see xfsdump retaining support for generating
all old formats.
Bill
