[6.9.0] /etc/profile.d changes are breaking ability to spawn shells in certain directories

Attempting to start bash shells in specific directories under tmux fails.

Upon investigating it seems these lines in /etc/profile have cause all login shells to forcibly open in /root

# limetech - modified for unRAID 'no users' environment
export HOME=/root
cd $HOME

This didn't occur in the last stable version 6.8.3 or earlier.

Workaround is to edit the /etc/profile to remove the offending lines.

I don't understand the rationale behind this.
