No problem here. I installed once 5.0-current with the current floppies.
Then I reinstalled 4.2 from those same floppies. The way to do that is to
change the name of the desired distribution under the options menu in
sysinstall. I dis not let sysinstall repartition my disk, since 5.0 booted
from it. I did force the newfs option in the disklabel assignment. I am
now running 4.2, which is running stable, as opposed to 5.0 which crashes
a lot.

I have bsd installed on ad4.. and my second disk is ad6. Have you had any luck with vinum? Ive been pulling out my hair trying to figure out how to add objects with it.
