Just made an ext2 partition on the very same box which has reiserfs (SuSE
8.2, Perl 5.8.0, patches) and tried the empty file test. Same error,
Inappropriate ioctl for device. In an attempt at falsifiability, deleted
the file and the error is No such file or directory on open (not read). I
think that rules out reiserfs.

The entirety of the program:

#!/usr/bin/perl -w
use strict;

open (FOO, 'foo') or die "open: $!";

my @lines = <FOO> or die "reading: $!";

close FOO or die "close: $!";

__END__

(for YS-T)
