The sysmobts-2050 machine does inherit from the generic bts so
we do not need an exact copy of the configuration file.
The watchdog is not used in dora or later images as this functionality
is integrated into the systemd.

The build differs in that it doesn't use a getty on ttyS0. In the fuutre,
a modified kernel serial driver as well as a 2050-specific utility
for managing the supervisor processor will follow.
systemd is using the depedencies of the LSB section and according to
the debian documentation all applications accessing /var should depend
on the localfs. This makes the watchdog start properly on systemd systems.
