Re: libzstd :: non-regular file test failure

BTW, the /dev/zero holds the following translator entry:

    $ showtrans /dev/zero
    /bin/nullauth -- /hurd/storeio -Tzero

I'm having a hard time finding the code handling the "-Tzero"
parameter. But, from a quick look at the arguments of storeio, it is
readonly by default. Maybe that has something to do with the write
operation making the close fail.
