Does this bug matter for you?

Not really :) but i can have a look.

No issue with 3.X (and debug>1) ?

I think we need a default DBEngine for commend install

I dislike to have :

[shnoulle@poledra master]$ php application/commands/console.php install
You have to set admin/password/full name and email address on the command line like this: php console.php install adminname mypassword fullname emailaddress [verbose]
[shnoulle@poledra master]$ php application/commands/console.php install DenisChenu password DenisChenu denis@sondages.pro
CException: Environment variable DBENGINE is empty, should be either MyISAM or InnoDB in /mnt/data/shnoulle/nginx/www/master/application/commands/InstallCommand.php:122

Then :

1. Allow DBENGINE in params
2. Set a default

PS : we need a set a default for each ... and maybe a console.php install -u=DenisChenu -p=Password .....

Else : no error, no issue when

$ DBENGINE=MYISAM php application/commands/console.php install DenisChenu password DenisChenu denis@sondages.pro
[shnoulle@poledra master]$ grep debug application/config/config.php 
    // debug: Set this to 1 if you are looking for errors. If you still get no errors after enabling this
        'debug'=>2,
        'debugsql'=>0, // Set this to 1 to enanble sql logging, only active when debug = 2

PS : maybe add a return 0 and a echo "Setup was done with success" ?

There's an index that won't work because the varchar is too long.

Wait, I already said that. Hm.

I won't look at this now, since there are lots of other high-priority issues.

I can't reproduce :)

You must set debug = 2 to get the error.

see $ grep debug application/config/config.php

PHP version maybe ?

I just tested this and it all works, now.
