There is a whole world outside the base system: munin, webmin, > nagios etc. Are you going to change all of them as well? >=20 Well, another way it could be handled would be to put the sysctls and the global variables they manipulate in a module shared by both clients, like sys/nfs/nfs_lock.c (module "nfslock"). Then the same sysctl would affect both clients. (I hesitate to create "yet another" module just to share the sysctls, but since "nfslock" is used by both clients, it should work ok, I think.) What do you think of that? If anyone else reading this has an idea/opinion, please let us know. rick
