postfix should be preseeded appropriately when pulled in by the UEC cluster controller installer target

[Etienne Goyer]

Binary package hint: debian-installer

In karmic, the d-i Eucalyptus cluster controller target bring in postfix as a dependency of eucalyptus-cloud. The Eucalyptus CLC needs a local SMTP server to send emails for user management (requesting account, approving account, etc). To spare the user from having to decide, out of the blue, how the local SMTP server needs to be configured, we should preseed postfix with value appropriate for the CLC installation. In particular, postfix/main_mailer_type could be preseeded as "Local only", as the cluster controller is not intended to receive of process email from the outside.

I think eucalyptus-udeb should take care of this, since it's the only thing with policy knowledge about whether it's installing a CLC rather than something else.

[Thierry Carrez (ttx)]

I agree it's one of the most annoying questions when installing UEC currently, and our mandate is to make it as simple as possible. Dustin, do you think it can make it into 10.04 ? If yes, the sooner the better, as this could be considered a "feature"...

[Dustin Kirkland  (kirkland)]

And I'll agree with Thierry and Etienne -- we should be able to agree upon a sane default for postfix in UEC installations.

Personally, I choose "internet site", but without any real consideration. That's the default value offered by Postfix, and I just peck the ENTER key on through.

[Dustin Kirkland  (kirkland)]

Assigning to Colin, as he offered to handle this as soon as we agree upon a key/value pair:

<cjwatson> preseed it with owner 'postfix'
<cjwatson> it's a little fiddly, point me to a bug and I can do it
<cjwatson> oh, that bug
<cjwatson> give me the key/value pair(s) you want preseeded

This bug was fixed in the package eucalyptus - 1.6.2-0ubuntu4

eucalyptus (1.6.2-0ubuntu4) lucid; urgency=low

  [ Colin Watson ]
  * Preseed postfix/main_mailer_type to "Internet Site" for cluster
    controller installations (LP: #455746).

  [ Scott Moser ]
  * only show ramdisk-id in metadata service if present for booted

So this worked okay when the CLC and CC were on the same system, but not when the CLC and CC were separated. I think we might need to relocate this bit. I'm going to reopen the bug for now. Not a blocker for A3 imho.

This bug was fixed in the package eucalyptus - 1.6.2-0ubuntu5

---------------
eucalyptus (1.6.2-0ubuntu5) lucid; urgency=low

  [ Colin Watson ]
  * Preseed postfix/main_mailer_type on the cloud controller, not the
    cluster controller (LP: #455746).

  [ Dustin Kirkland ]
  * debian/eucalyptus-cc.postinst, debian/eucalyptus-udeb.finish-install,
    debian/eucalyptus-cc.templates, debian/eucalyptus-udeb.postinst:
    - Have the CLC add it's IP address to the served preseed file, such
      the CC can pick it up and write it to eucalyptus.local.conf
      as the required VNET_CLOUDIP value (on separated CC, CLC installs),
