Does each jail need to have its own proc filesystem mounted ? The original jail documentation says to do that, but I have heard rumors that this is not necessary. What is the negative ramifications (if any) to running a jail without its own seperately mounted proc filesystem ? (I have a test machine with ten jails on it, and I have ten extra proc filesystems mounted - I would like to avoid this if possible..) 2. Does kern.maxproc scale in a linear fashion with maxusers ? 3. is kern.maxvnodes determined automatically based on other settings, or do I ever have to tune this myself by hand ? 4. Why is it that some linux utilities, run inside a jail, get the hostname of the host machine, and not the hostname of the jail itself ? I am successfully running linux apps in jails by using linux compat on the host system and running linux.ko, but sometimes these linux apps get the wrong hostnames.... Thanks!
