We can either make the mem file in the procfs owned by group kmem and group readable, or we can make everything that needs this be setuid root as you have done above. The problem with making mem gid kmem is that it current has the uid and gid of the running process. If we change this, then this will no longer be true. This is probably of marginal utility, so we should probably change it group kmem. I'm open to other opinions... -DG
