If more than just NFS was defining its own sysctl variables, I might be worried but as I found out when I did the original dynamic sysctl work, only NFS actually used the (IMHO) ugly mechanism for rewiring its oid number by putting a pointer to the oid in its struct vfsops. Since sysctlbyname exists and is obviously a better mechanism for reading the variable (based on code complexity), then why not use it? We maintain both nfsstat and mountd in our tree and I don't see anyone expecting to be able to run Net/OpenBSD versions of those utilities on FreeBSD. If people feel strongly that we should continue to support the old mechanism, I guess I could modify vfs_register to change the oid numbers. It doesn't really seem worth it to me though. -- Doug Rabson Mail: d...@nlsystems.com Nonlinear Systems Ltd.
