It looks like NetBSD's "dump" (1.6.1 version) outputs dump archives
that give the Solaris 9 "ufsrestore" indigestion:

solaris9:1:51 [/export/home] # rsh NetBSD "dump 0usf 100000 - /dev/rsd2f" | \
ufsrestore -dvrf -

Never seen a dump | (remote) restore fail like this before.  Any idea why?
Is the output of "dump" so far removed from the way it used to be that
it no longer is recognizable to other UFS/FFS apps like "ufsrestore"?

It fails almost immediately:

Conversely, any chance anyone's ported NetBSD's "restore" to Solaris instead?
