Well, not exactly ;-) And, yes, I'm aware of "resetconfig" command.
Possibly, I was not clear enough; I should also mention 'detach' command.
Detaching without -f option also does not work usually.

As for 'rm' command, it tends to fail in similar way ;-)

Which is worse, it at lease seems that some objects got slided and slightly
resized after multiple detach/attaches; but I should track this down more
precisely, and currently in lack of spare system.

Stay tuned ;-)
