This commit created a bug:

 
https://github.com/openSUSE/aaa_base/commit/b9a57d5a64b3d2d09bc591f894f6558f1945df70

The bug is that "unset is" was added to /etc/profile.

That causes "is" to get unset on bash.bashrc when /etc/profile is invoked here
(line 326):

    if test \( -n "$SSH_CONNECTION" -o -n "$SUDO_COMMAND" \) -a -z
"$PROFILEREAD" ; then
        _SOURCED_FOR_SSH=true
        . /etc/profile > /dev/null 2>&1
        unset _SOURCED_FOR_SSH
    fi

As a result, all code following this point in bash.bashrc that depends on
variable $is is broken.

In particular, the sourcing of bash.bashrc.local.

WTF this commit is attempting to do is unknown because the bug that motivated
it is not public.

Here's a proposed fix:

My recommendation is that if these files are going to be sourcing each other,
then because bash has a global namespace, each file needs to use variable names
that have some unique prefix or something.
