Running drush on Aeegir sites as a regular user
Warning: this part of the manual is in experimental mode, that is, this hasn't been tested and you shouldn't be running this in production. Consider this cutting edge research material notes.
What's the problem here?
As things stand, you cannot run tasks as a regular UNIX user on your Aegir Drupal sites:
anarcat@marcos:~$ drush @hostmaster cc all
A Drupal installation directory could not be found [error]
The drush command '@hostmaster cc all' could not be found. [error]The reason the site is not found is because the alias cannot be loaded. If we change our home directory to find the alaises, we then get permission problems:
anarcat@marcos:~$ env HOME=/var/aegir drush @hostmaster cc all
include(/var/aegir/.drush/platform_hostmaster.alias.drushrc.php): failed to open stream: [warning]

A Drupal installation directory could not be found [error]
The drush command '@hostmaster cc all' could not be found. [error]... so that doesn't seem to be a good approach, although one could just fix the permissions on the alias files for the site (which don't contain the DB password, oddly enough) and platforms (which have been safe since the "server" seperation):
cd /var/aegir/.drush
chmod a+r ls *alias* | grep -v 'server'Then we end up with another problem:
Cannot open drushrc "/var/aegir/hostmaster-HEAD/sites/aegir.anarcat.ath.cx/drushrc.php", [warning]

Cannot open drushrc "/var/aegir/hostmaster-HEAD/drushrc.php", ignoring. [warning]

/usr/share/drush/includes/drush.inc:820) install.inc:619
Drush command could not be completed. [error]... and this is really the core of the issue here: we need to allow more than one user to access those files, and aegir must be able to fix those permissions when the site is created/verified.
