- The error may well occur for "/grav0"; note that it says "exportfs:
- Full_Clients: unknown host" before it says "re-exported /grav0". Sounds
- like it's complaining about "/grav0", as well as "/home" and
- "/export/exec/kvm/sun4c.sunos.4.1.1".
-
- Those happen to be the files where the "root=" entry contains a netgroup
- rather than a list of host names.
-
- "-access" checking is done by "rpc.mountd", and it's willing to look up
- netgroups.
-
- "-root" and "-rw" checking is done by the NFS server code in the kernel,
- and it's unwilling to look up netgroups; instead, "exportfs" has to
- shove an explicit list of IP addresses for the hosts in the host list
- into the kernel, and it's unwilling to construct such a list from the
- current contents of the "netgroups" map.
-
- In other words, you don't get to put netgroups into "-root=" or "-rw="
- entries.
