> TOPIC #2 of 2: Distro upgrade
> As mentioned above, we're overdue to do a major upgrade of www.svlug.org
> to 14.04.1 LTS (Trusty Tahr).
> Upgrades are a little dangerous generically. Prerequisites:
> 1. Have an utterly complete system backup.
I cited a list of five things at minimum to back up, in a previous message.
It would also be a good idea to back up /var/svn , as sixth item.
This matter was already documented by site-docs/package-operations :
5. You will occasionally want to run 'do-release-upgrade' as the root
user, to check for a newly available Ubuntu Server branch and transition
to it. If do-release-upgrade informs you of an upgrade option, that
would be an utterly excellent time to cancel and (before re-running
'do-release-upgrade') grab these and copy them offsystem as a
last-resort fallback option in case something goes terribly wrong:
dpkg --get-selections "*" > /root/selections-$(date +%F)
tar cvzf /root/etc-$(date +%F).tar.gz /etc
tar cvzf /root/webroot-$(date +%F).tar.gz /var/www/svlug-main
tar cvzf /root/svnfiles-$(date +%F).tar.gz /var/svn
tar cvzf /root/sitedocs-$(date +%F).tar.gz /usr/local/src/site-docs
tar cvzf /root/rootsensitive-$(date +%F).tar.gz /root/sensitive
