This is a daily mail from my Alix router.
I do a dump in daily.local (see below)
and most of the time it works just fine.
Occasionaly though, the DUMP fails saying

That puzzles me, as I dump to stdout,
redirecting to a file (see below).
(I vaguely remember that the reason I switched from
"dump -f file.dump ..." to "dump -f - ... > file.dump"
was that I was advised her by a developer about
the tape legacy of dump, but I forgot what exactly
was the problem then and can't find it in archives.)
Why would "dump -f - ... > file.dump" think
that it reached an end of tape?
