Once again Ubuntu Linux proves itself to be easy to upgrade. Going from 9.04 to 9.10 (one release newer, since their numbering is bsaed on dates) was easy, but included the standard sprinkling of manual re-customization that I’ve come to expect from Debian based systems.
I did the Network Upgrade for Servers.
I had to re-customize these files since I’m not running with 100% default configuration:
/etc/monit/monit
/etc/monit/monitrc
/etc/dovecot/dovecot.conf
/etc/apache2/apache2.conf
/etc/php/apache2/php.ini
I basically did a manual diff side by side in Emacs and copied my changes over into the new config files. Reboot, no problems. Nice.
