multi-platform support

I'm getting the exact same issue. What happens is, it tries to use the new platforms path to drush, rather than the main, installed, D5 version of drush etc.

Each platform will need drush installed (as it might need multiple versions of drush).

The trick here is figuring out the path to the drush for that platform.

Marking this as priority normal, as the 0.1 SPECIFICALLY does not support multiple platforms.

I intend to store a set of configuration files that will be called instead of drush, for each of the sites.
got the idea from : http://drupal.org/node/250843

So instead of calling
/path/to/drush command --uri=domain --root=something

we will call :
PROVISION_CONFIG_PATH/drushrc/domain.com command

This will also centralize the interface for platforms on remote servers.

If it doesn't support it yet, then it's a feature request, not a bug :P

"Each version will need drush installed" -- hmm, OK, not sure that makes sense -- that's almost like needing a whole hostmaster install profile for each platform? Or just drush for each version of the platform?

But then, it looks like the config files you are thinking of obsolete that. Does that mean no longer using drush? Not clear to me...

it actually works already, just lacking a good way of popping up new platforms.

I cleaned it up a little bit, and started qorking on a provisionslave profle, to install a headless provisioning system. Probably forcing it to install in the default directory. So provision can redirect for non existing sites pointing to it

Also want to make provision configured via a config file and not the interface. This will make it a lot simpler on both sides.

I created a number of tickets to break this down into easier pieces for us :

Primary requirements :
http://drupal.org/node/321953 - location of drush.php

Related requirements :
http://drupal.org/node/321940 - force provision / hostmaster sites into sites/default
http://drupal.org/node/321949 - create headless slave profile for backend.

That will at least allow us to host multiple platforms simply, and get on with the D6 port of provision.

To make this all really slick (think 0.2 release and non-experimental platforms) :

http://drupal.org/node/321942 - Provision only configured through config file. Simplifies both modules and lessens hosting's dependence on provision
http://drupal.org/node/321944 - A setup command for creating the provision config file, that we can call from front ends. So adding a new platform becomes a 2 form process.
http://drupal.org/node/321946 - Simple front page for slaves, with some help on how to configure / link with a hostmaster. Just documentation mostly.

completed :
http://drupal.org/node/321953 - location of drush.php
http://drupal.org/node/321940 - force sites/default
http://drupal.org/node/321944 - basic setup command working now. creates drush symlink

in progress :
http://drupal.org/node/321949 - HostSlave profile. Working, but needs some more love before creating project node and importing.

not started :
http://drupal.org/node/321946 - Simple front page for slaves.
http://drupal.org/node/321942 - Config files. I am thinking seriously about this though. It simplifies a lot of code.

I can now somewhat easily pop up new platforms, but it still requires a lot of legwork that should be unnecessary.

I'm seriously considering the config file ticket because it simplifies the D6 and all future ports a decent amount.

Now works.

Just needs http://drupal.org/node/321946 , but that is a documentation issue.
