To take installworld as an example, what I do is: > > # cd /usr/src > # mount -u -o rw /usr > # make installworld > # mount -u -o ro /usr This sounds similar to problems I had more than a year ago. I was trying to run with a readonly /usr, and needed to mount it rw occasionally to install things etc. The long and short of it was that I was never able to get this to work reliably, because I had fairly frequent kernel panics and inconsistent file systems. As soon as I stopped trying to change /usr between ro and rw, the problems disappeared.
