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.
