A reasonable solution to this is to allow a command line argument to
specify an alternate /etc/dumpdates file.  This way you can have multiple
consistent dumps done simultaneously.

Dump upto 4.3bsd-reno doesn't have such an option unfortunately. (would
be nice!)

A workaround is to maintain multiple /etc/dumpdates yourself, by using a
wrapper script for alternate sump sequences that mv's /etc/dumpdates to a
safe place, the alternate one in for the alternate dump, then out again
and restores the original one afterwards.
