Secure MySQL installation on Ubuntu 12.04 LTS so it doesn't break Aegir install/functionality

I ran into an issue installing aegir on the new ubuntu today and steven asked me to add this bug. In the end i was able to get it to install. It MIGHT have worked perfectly out of the box but i forgot to fix my dns in hosts before installing and it failed out the first time. I tried to remove, configure dns and reinstall but it kept failing for a variety of reasons (permissions on conf files in var/aegir, etc) so i removed via apt-get then manually purged the db user aeiger created, the system user, the directory (var/aegir) and then reinstalled via apt-get install. Worked perfectly after a long pause here:

installing the Aegir frontend (Drupal with the hostmaster profile), please wait...
+ su aegir -c cd /var/aegir && drush hostmaster-install --yes --debug --backend titanium.favish.com | drush backend-parse
Bootstrap to phase 0. [0.01 sec, 2.8 MB]                             [bootstrap]
Drush bootstrap phase : _drush_bootstrap_drush() [0.01 sec, 3.02 MB] [bootstrap]

Here is also a transcript of IRC to assist anywhere im nclear above:

michaelfavia ive installed aegir via deb successfully about a half dozen times.
michaelfavia but im installling on a fresh ubuntu 12.04 and having an issue it seems.
michaelfavia id like to eliminate dns issue. it is for a local setup.
darthsteven what issue are you having?
darthsteven michaelfavia: what issue are you having?
michaelfavia darthsteven, well the package doesnt install. n debug mode it complains about permissions on the conf files that are in /var/aegir
darthsteven I've not tried to install it myself on 12.04, could you pop some relevant logs into an issue on d.o?
* cdracars has quit (Read error: Connection reset by peer)
michaelfavia darthsteven, happily. id liek to remove the possiility that my stupidity befor ei wast ebug counts on it thoguh
michaelfavia if i use my own fqdn titanium.favish.com on the machine.
michaelfavia i can just enter it into hsts right??
michaelfavia /etc/hosts
darthsteven that should be the case
* cdracars (~anonymous@164.58.23.135) has joined #aegir
michaelfavia darthsteven, and whats the deal with 127.0.1.1 should it go there or on 127.0.0.1?
darthsteven either I think, but I tend to go for 127.0.0.1
michaelfavia darthsteven, me as well :)
michaelfavia im just trying to make sure it isnt a hostname issue that i send someoen chaning down.
michaelfavia chasing
michaelfavia darthsteven, which logs would be helpful?
michaelfavia output from the debug install i assume.
michaelfavia anything else?
darthsteven yup
darthsteven not that I can think of
michaelfavia ok one sec.
* obicke (~omar@bas5-montreal28-1177916882.dsl.bell.ca) has joined #aegir
* rv0 has quit (Quit: rv0)
michaelfavia darthsteven, interesting. after a manual delettion of aegir remanants it installed successfully
michaelfavia i wen thtorugh and manually removed the aegir user, folder, etc
darthsteven hmm...
darthsteven strange
michaelfavia which were oddly left after a at remove
michaelfavia s/at/apt
darthsteven could you log an issue about installing on 12.0, we should probably test that at least :)
* oadaeh has quit (Quit: Quitting)
michaelfavia darthsteven, of course.
michaelfavia darthsteven, for what its worth the FIRST time i tried to install i forgot to configure the host and it failed. so i removed all the packages.
michaelfavia and tried again after configuring
darthsteven could you pop that on the ticket too please?
darthsteven could you raise it as a 'task'
michaelfavia darthsteven, you got it
