For commonly done items, please see the 5COMMON ITEMS: section later in the file. These instructions assume that you 6basically know what you are doing. If not, then please consult the FreeBSD 7handbook. 8 --- 8 unchanged lines hidden (view full) --- 17 system performance. If you want to do performance measurement, 18 benchmarking, and optimization, you'll want to turn them off. This 19 includes various WITNESS- related kernel options, INVARIANTS, malloc 20 debugging flags in userland, and various verbose features in the 21 kernel. Many developers choose to disable these features on build 22 machines to maximize performance. (To disable malloc debugging, run 23 ln -s aj /etc/malloc.conf.) 24 | 1Updating Information for FreeBSD current users 2 3This file is maintained and copyrighted by M.

| 2520110427: 26 The default NFS client is now the new NFS client, so fstype "newnfs" 27 is now "nfs" and the regular/old NFS client is now fstype "oldnfs". 28 Although mounts via fstype "nfs" will usually work without userland 29 changes, it is recommended that the mount(8) and mount_nfs(8) 30 commands be rebuilt from sources and that a link to mount_nfs called 31 mount_oldnfs be created. The new client is compiled into the 32 kernel with "options NFSCL" and this is needed for diskless root 33 file systems. The GENERIC kernel configs have been changed to use 34 NFSCL and NFSD (the new server) instead of NFSCLIENT and NFSSERVER. 35 To use the regular/old client, you can "mount -t oldnfs ...". For 36 a diskless root file system, you must also include a line like: 37 38 vfs.root.mountfrom="oldnfs:" 39 40 in the boot/loader.conf on the root fs on the NFS server to make 41 a diskless root fs use the old client. 42 |
