 ```

-The setting can be made persistent through reboots by adding the line

 Additionally, Redis has fairly serious latency issues with THP (Transparent Huge Pages) enabled, so it is best to disable it. Disable them by running:
 ```
 echo never > /sys/kernel/mm/transparent_hugepage/enabled
 ```
-This configuration is also not persistent through reboots. Redis recommends adding the command as a line to your `/etc/rc.local` file, but `rc.local` is deprecated, so we will instead create a systemd unit to disable THP at startup. Create a file `/etc/systemd/system/redis-disable-thp.service`, with the following contents:
-```

-Description=Disable Transparent Huge Pages (THP) for Redis
-DefaultDependencies=no
-After=sysinit.target local-fs.target
-Before=lxd.service

-Type=oneshot
-RemainAfterExit=yes
-ExecStart=/bin/sh -c 'echo never | tee /sys/kernel/mm/transparent_hugepage/enabled > /dev/null'
-
-[Install]
-WantedBy=basic.target
-```
-Then enable the service by running:
-```
-systemctl enable redis-disable-thp
-```
+You can make these settings persistent accross reboots by adding them to the container start script in `/etc/containers/startup.sh`.
