Here is the question at > subject. Thanks! Correct. If you are not afraid to patch the system: zfs has the JAIL =20 flag set, you just need to do the same with nfs. To do this edit src/sys/nfsclient/nfs_vfsopts.c, search VFS_SET and =20 change it to VFS_SET(nfs_vfsops, nfs, VFCF_NETWORK|VFCF_JAIL); I suggest to not do this with tmpfs if you do shared hosting (you =20 don't want that strangers eat up all your physical RAM).
