1. Swap the order of the `numactl` and `zone_reclaim_mode` commands. This is better because if a user manually follows the old steps, they may run `numactl --interleave=all mongod` *before* fixing `zone_reclaim_mode`, and thereby still receive `zone_reclaim_mode` startup warnings. 2. Adjust the `zone_reclaim_mode` command to be an appropriate sudo-style command (simply prepending `sudo` won't work), indicating that the command needs to be run as root (and how). Also provide a more modern `sysctl` based variant (again with sudo). 3. Add `<options>` to the `numactl` command to indicate that these can be specified if desired. 4. "may" -> "should" 5. "including ..., or clients" -> "including ..., and clients"
