Does anybody know what do-release-upgrade -q actually does?

Hopefully it does the upgrade without the need to interact with it, if this is the case does it overwrite configs or keep the originals?, or does it do something else?

Okay so I looked into this by testing it, I Installed a virtual Ubuntu 10.04 edited some config files and ran do-release-upgrade -q,

It ran exactly the same I had all the same questions to answer regarding mysql passwords, and modified configs.

This led me to look at the code to figure what it exactly does. The code for do-release-upgrade is here

Looking through it looks like using the -q option simply omits a tiny bit of output.

This is the only stuff it omits as far as I can tell.

if not options.quiet:

    print _("Checking for a new ubuntu release")

..

if not options.quiet:

      print _("No new release found")

...

if not options.quiet:

      print _("Release upgrade not possible right now") 

      print _("The release upgrade can not be performed currently, "

              "please try again later. The server reported: '%s'") % m.new_dist.upgrade_broken

    sys.exit(NO_RELEASE_AVAILABLE)

It looks like this does nothing else other than omit the above output, which in the grand scheme of the upgrade output is minute to say the least.
