BOA Linode Install Experience

I am pleased to say I have successfully installed Barracuda and a satellite Octopus instance on my linode.
I have also managed to upgrade the two all using the scripts kindly provided by omega8cc.
During the install process I received a couple of errors but nothing show stopping.

/usr/bin/mysql_secure_installation: 371: find_mysql_client: not found

Which led me to:
http://drupal.org/node/1213050 "This is not our bug, it is MariaDB bug probably, but cosmetic only, since it doesn't break anything, AFAIK."

So that's cool, there was another error during install of Barracuda.

ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist

I really didn't sweat this one to be honest, bigger fish to fry as they say q8)

I have a couple of newbie questions

1. At the moment I can log in to chive using localhost as host and root as user with the password provided, it seems sensible to change that, I would think it should be ok but can't be 100% sure.

2. I added my ip address to /etc/csf/csf.ignore to exclude it, to prevent the login (from myip) notification emails only, it appears to be working as expected, am I correct that restarting nginx doesn't invoke this new setting? I used nginx start stop to get it working
   *(error/typo see edit at bottom of page)

I found this useful:

pdnsd - there is no interface/login/password (irrelevant)
Bind9 - there is no interface/login/password (irrelevant) unless you will use Webmin
Solr - see docs/SOLR.txt
Chive & SQL Buddy - always site db credentials from settings.php per site
CGP - is not password protected
Webmin - standard setup - your server root password

I couldn't see the database credentials in the settings.php or the drushrc.php files but I was able to use the command:

drush @example.com sql-connect

I later realised I was looking at
/data/disk/o1/distro/001/platform/sites/default/settings.php
instead of
/data/disk/o1/distro/001/platform/sites/mysite.com/settings.php

I do have one email when logged in as root that contains:

W: Failed to fetch http://ftp.osuosl.org/pub/mariadb/repo/5.2/debian/dists/squeeze/Release.gpg Could not connect to ftp.osuosl.org:80 (140.211.166.134), connection timed out

W: Some index files failed to download, they have been ignored, or old ones used instead.

1. I might be wrong but are these just warnings about translations that failed to download for il8n module? I have not investigated this any further as of yet.

I also recieved this email message

Action: Too many hits for LF_DIRWATCH - Directory Watching disabled

1. I was thinking this might be due to all the changes when updating, is this something that requires further attention? Does it sort itself out and automatically re-enable? or do I need to take further action?
   I have not investigated properly yet but I did see something about /tmp that makes me believe it is somehow related, and possibly I need to manually clear /tmp regularly.

A little perseverance and BOA rewards one greatly, I am really impressed with the setup it seems a little more complex to get orientated than standard aegir install but that's understandable considering the use case's BOA covers, thanks very much for all the hard work folks @omega8cc and most of all, thanks for sharing! X <-- A big kiss!

EDIT
I must of been well tired when I wrote this:
"restarting nginx doesn't invoke this new setting? I used nginx start stop to get it working"
Well it's half right lol, I do believe lfd is what needs to be restarted and restarting I think does actually work.
service lfd restart (command I used)
