I checked a couple more 16.04 systems and they don't use symlinks. So
that is odd that we're seeing differences.

Yes, /usr/bin/perl and /usr/bin/perl5.22.1 are the same inode.

Where can I find this in the Python source code?

I'm looking at the Python 2.7.15 source tarball, as downloaded from
python.org, and there is nothing named python-exec* anywhere in the
tree. This is after building and installing to a tmp dir, so my find is
searching source, build projects, and installed files. Likewise for
Python 3.6.5.

That's what Debian is doing in this regard.

Stock Python 2 installs:
python -> python2
python2 -> python2.7
python2.7

Stock Python 3 installs:
python3 -> python3.6
python3.6

Debian Python 2 installs:
python -> python2.7
python2 -> python2.7
python2.7

Debian Python 3 installs:
python3 -> python3.6
python3.6

The only difference is that Debian's python symlink goes directly to
python2.7 rather than using the intermediate python2 symlink. This has
identical results.


For both versions of Python (unpatched, from python.org), I did:
./configure --prefix=/usr
make
DESTDIR=tmp make install

Here are the executables installed, none of which are this loader:
