After that I reenabled them. The only thing which I think might be a serious problem is if you choose a dump device where there is not enough space. dumpon(8) says one has to have 64 KByte more space there than one has main memory. Doing this wrong shouldn't be fatal I think as sd and wd seem to check for having too few space and don't dump in such a case.
