This one is somewhat less critical IMO, since this RPC is just fyi for the mountd on the server and, if it fails for any reason, only normally affects the output of "showmount" and doesn't break the umount. (That doesn't mean I don't think it should be fixed, but it can be done separately from resolving what mount_nfs needs to default to.) rickReceived on Mon Sep 14 2009 - 14:22:34 UTC
