Comment (by Christian Mauderer):

 Thanks for the suggestion. Just to make it clear: I wouldn't like big
 changes in the FreeBSD sources either. The target should _not_ be to
 replace existing functionality with new code. The target would be to find
 locations where the garbage collection doesn't work. For example: As soon
 as WLAN is enabled (net80211 = on) ifconfig needs some additional stuff.
 To prevent the linker pulling that always in there is a #ifdef in


 I assume that the same is true for some other functionality. For example:
 Do we always need the "vlan" functionality in ifconfig? Or would it be
 possible to disable it?

 Run-time memory effects are a lot harder to analyze. Of course that would
 be nice too but I'm not sure whether someone who is new to RTEMS has the
 insight that is necessary to analyze that or has the insight to see the
 use cases that we have.
