Thanks for asking a great question.  I somehow expected that we
probe in init-db.c::create_default_files() for this when we probe
for case sensitivity, symlinks, etc., but apparently we don't.

I guess we don't because on some filesystems we can't.  IIRC, it
goes something like: chmod immediately followed by lstat pretends
that change to the executable bit stuck, until the in-core buffer at
the vfs layer is flushed to the disk platter that holds the
filesystem without any notion of executable bit.
