[ECOS] newbie questions

Does that mean that a configuration carries around information inside itself
telling it what template it originated from, in order to calculate the
differences between it and that template?

The configuration of an eCos system is saved in a .ecc file. This is
normally called ecos.ecc by ecosconfig, but the configtool can give it
other names. The save and load in the configtool operate on this file,
loading and saving the current configuration.

The ecos.ecc file is quite big, 1/2 MByte is typical since it contains
a lot of information. .ecm file contains the differences between the
current configuration and the default configuaration for a particular
template. This is much smaller than the .ecc file becasue you
typically only change a few configuration options. The export command
will generate such an .ecm file and import will apply the list of
changes to the current configuration.
