Yes, the test reproducibly passes for me. But the filesystem I am
using is ZFS:
$ yes "" | sed -e '765 q'> /tmp/small-text-file.txt ; \
dd if=/dev/urandom bs=765 of=/tmp/random-data.bin count=1 ; \
cp /tmp/random-data.bin /tmp/small-text-file.txt . ; \
find \

small-text-file.txt \
-printf '%%k=%k %%b=%b %s %p\n' ; \
sha1sum /tmp/random-data.bin random-data.bin
