Aegir 3.x appears to work nicely with Drush 7.x. However, I've only been able to test this by installing Aegir on Drush 6.x, and then upgrading Drush to 7.x.

Attempting to install Aegir 3.x on Drush 7.x results in the following error:

apache on aegir3.dev could not be restarted. Changes might not be available [warning]
until this has been done. (error: apache2: Syntax error on line 265 of /etc/apache2/apache2.conf: Could not open
configuration file /etc/apache2/conf.d/aegir.conf: No such file or directory
Action 'graceful' failed.
The Apache error log may have more information.)

Now /etc/apache2/conf.d/aegir.conf is just a symlink to /var/aegir/config/apache.conf, but this file doesn't exist. In fact, it's only supposed to be a further symlink into the server_master directory. But the config/ directory seems to have more problems than that:

aegir@aegir3:~/config$ tree
.
├── self
└── server_master
    └── apache
        └── vhost.d
            └── aegir3.dev

The server configs seem to be failing entirely (and silently).

Some settings have not been provided and will now be prompted.
Don't worry: you will get to review those settings after the final install
MySQL privileged user ("root") password:

This script will operate the following changes in your system:

1. Create server-level configuration directories
2. Create the Hostmaster frontend platform
3. Install the frontend site
4. Setup the dispatcher (a user cron job)

 * you have read and are following the install instructions at:
    http://community.aegirproject.org/installing
 * the FQDN of this machine is valid and resolves
 * you are executing this script as your "aegir" user

The following settings will be used:
 Aegir frontend URL: aegir3.dev
 Master server FQDN: aegir3.dev
 Aegir root: /var/aegir
 Aegir user: aegir
 Web group: www-data   
 Web server: apache
 Web server port: 80   
 Aegir DB host: localhost
 Aegir DB user: root

I experienced this issue as well. There may be some sort of race condition because after I manually ran drush make for the first time, and only that once, it created a vhost file and installed the modules. It still erred out in the end. I will post the log I kept when I can pull it from my server.

The commit to Drush that had originally broken Aegir 3.x is b1e308290. Aegir will install at that commit now. So it's something that went into Drush since then.

Bumping to critical, since we need Drush 7.x to be able to support Drupal 8 sites.

Git bisect to the rescue:

24addcdd08aa422aa00e2a11194a74c212a602ec is the first bad commit

    Fix #555. Move the set of DRUSH_BACKEND context from _drush_bootstrap_output_prepare() to _drush_bootstrap_global_options().

I'll have to take a closer look at what that commit does, but I can confirm that it's the first one to break Aegir's hostmaster-install.

Here's my log if it helps. I ran drush make so hostmaster-7.x-3.x dev already existed and it bootstrapped just this once. The apache config was left in a bad state.

file was way to long to include here, let me know if you want it, I did --debug, but the only error I see is that it's trying to create a site, http://default in the sites directory when settings.php does not exist in sites/default

It looks like this was a latent bug in Drush. See: https://github.com/drush-ops/drush/pull/684

With that simple fix to Drush, Aegir installs on Drush master again.

It seems like the link in #8 hasn't been committed yet, is there a way to install drush via composer with that commit included?

This is whats happening on my setup atm:

Some settings have not been provided and will now be prompted.
Don't worry: you will get to review those settings after the final install
MySQL privileged user ("root") password:

This script will operate the following changes in your system:

1. Create server-level configuration directories
2. Create the Hostmaster frontend platform
3. Install the frontend site
4. Setup the dispatcher (a user cron job)

We are making the following assumptions:
 * you have read and are following the install instructions at:
    http://community.aegirproject.org/installing
 * the FQDN of this machine is valid and resolves
 * you are executing this script as your "aegir" user

The following settings will be used:
 Aegir frontend URL: aegir.ld
 Master server FQDN: aegir.ld
 Aegir root: /var/aegir
 Aegir user: admin
 Web group: www
 Web server: nginx
 Web server port: 80
 Aegir DB host: localhost
 Aegir DB user: root
 Aegir DB password: <prompted>
 Aegir DB port: 3306
 Aegir version: 7.x-3.x-dev
 Aegir platform path: /var/aegir/hostmaster-7.x-3.x
 Admin email: brian@realityloop.com
