Did you try changing for a simpler command (e.g. one that just echoes something
to the interfaces file) to ensure it's running *at all*?

Pass "debug-ubiquity" in your boot command line (in syslinux.cfg, in addition to
e.g. automatic-ubiquity) to get more debugging. Then, once the system is
installed, you can look in /var/log/installer and grep for the command you
added, to see if it's running.

I'd try sidestepping the "\n" issue, you can use this command to delete the line
containing "auto eth0" and the following one (which I believe are the ones added
during the installation and that you'd want to eliminate):

ubiquity ubiquity/success-command string \
in-target sed -i -e '/auto eth0/,+2d' /etc/network/interfaces

I haven't really tested it but it should be more reliable.
