With this change, distribution defaults are now read from the distribution defaults
directory, /usr/share/defaults/e2fsprogs. These files are expected to be the
sensible defaults required for basic operation.
Site administrators may still override the default configuration by placing the
files within the site config directory (i.e. /etc) - and those configuration values
will be read instead. The distribution files within the defaults directory are
percieved as immutable, and as such resiliant to upgrades over time.
A side effect of this stateless configuration is that a site admiministrator is
able to reset their configuration to the sane defaults by simply removing the files
they placed within the site configuration directory.
To users already making use of an altered configuration within /etc, this change
is transparent and does not affect existing operation.
The fundamental goal within this change, and stateless itself, is to separate
OS configuration from the system administrator configuration.
