<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>This actually is something I wanted to verify.<BR>
What are the reasons sudo won’t work?<BR>
Apache running seems to be the only reason for that? Also the fact that config files are written to privileged locations (/etc/apache2...), volume group commands and such.<BR>
In the newer devstack I am working on sudo should work since the process of installing (to any location u pick) and then starting is separated (and the apache user/group is configurable) but I just wanted to double check this.<BR>

it runs as local user or if you ran it as root originally, it will create a user called stack change to that user and rerun itself.<BR>
(which means you will need to do sudo su stack; screen -x)<BR>
<BR>
If it isn't running as the stack user, you probably just need to rerun it.<BR>
