Expected result: - After the last NFS mount from a server has been unmounted, the correspond= ing entry in /var/db/mounttab, and the complete file if empty, should be remove= d. - This should enable rc.d/nfsclient to skip any further NFS server notifica= tion during shutdown. -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
