 Fixed
It turns out it was because I cheated on the get_plat_tags.sh script. I edited the script itself to return DEBIAN3.1 when it found 4.0 in /etc/debian_release. However, that was only the script used for installation, not the script that was installed within the package.
Hence my system had no idea what platform it was on, and breaking badly.
The proper workaround, until Debian Etch (4.0) is a supported Zimbra platform, as mentioned elsewhere, is to append "3.1" to the end of /etc/debian_release *before* running the installation. |
