Debian Sarge (oldstable) to Etch (stable) dist-upgrade
De gacq wiki
Package with manual intervention required
Postfix version 2.3.3-2 and later require changes in main.cf. Specifically, mydomain must be specified, since hostname(2) is not a fully-qualified domain name (FQDN). Failure to fix this will result in a broken mailer. Decline this option to abort the upgrade, giving you the opportunity to add this configuration yourself. Accept this option to automatically set mydomain based on the FQDN of the machine. Add mydomain entry in main.cf for upgrade?
Incompatible configuration file layout detected The Debian packages have changed the way they handle configuration files for amavisd-new to a better system, which uses multiple files instead of a single, monolithic file. The old amavisd-new configuration files that are still present in your system (named either /etc/amavisd.conf or /etc/amavis/amavisd.conf) are incompatible with this new config file layout. You should read /usr/share/doc/amavisd-new/README.Debian to understand the new configuration layout, and after that you should port your configuration to the new layout. For your safety, the old configuration files in your system have been disabled, and a ".disabled" postfix was added to their file names. The amavisd-new service will refuse to start until you remove (or rename) these ".disabled" files. This safety is in place to avoid starting an unconfigured amavisd-new in place of your previously configured one. Do not remove the ".disabled" files until you have read the /usr/share/doc/amavisd-new/README.Debian file and ported your old configuration to the new layout.
