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.
The idea is that the basic extension resides inside the the normal
recipe directories. Depending on the version of poky the bbappends
need to be included. Appends applying to all versions will be put
into the shared folder, specific ones into the specific directory.
Once a bbappend can not be shared anymore it needs to be copied.
