It's clear to me that a host box running multiple jails needs to expose that NFS mount to each jail. As far as I know, that means that NFS partition has to be mounted (redundantly?) for each jail, even in (in my case), they'll all be access in the the same way (eg. read-only). This seems to be that you'll quickly run into some effective upper limit as to how many NFS mounts a FreeBSD machine can handle (I'm using 4.7-R for my current experiments.) So, my question(s): - is my assertion correct; that is, do I need to redundantly mount the same NFS partition for each jail for each jail to access it? - if not, is there a mechanism for jails sharing a read-only NFS mountpoint?
