I was using NFS not for sharing between machines but rarely to add a bit of security an convenience: a host compromise on the named box could not modify the files (RO export), yet an internal client could update the zone file easily (ssh/kerberized telnet to the file server in question and edit the file) and a rndc reload would update the named. I can move away from that model easily enough, I just need to actually make a plan to do so. If NFS and chroot are unhappy bedfellows, I'll do so :-) -T -- "If knowledge creates problems, ignorance will not solve them" -- Isaac Asimov.Received on Wed Oct 06 2004 - 15:36:11 UTC
