Sympl determines host name incorrectly during install
During the install, sympl creates a 'default' directory based on the hostname of the machine. However, it incorrectly uses the domain 'localdomain' when creating this directory.
On a clean debian machine, the /etc/hostname file contains a bare hostname. Code in core/debian/postinst uses this file as the hostname, and if it sees a 'bare' hostname, appends 'localdomain' to the hostname read from the file.
The debian installation had a full hostname specified, and typing
retrieves this full host name correctly.
The postinst script will also fall back to using hostname -f if /etc/hostname exists.
