Then reconfigure `kernel-hooks` and reboot for it to take effect:
```
# apk fix kernel-hooks
# reboot
```
You can check the status of apparmor using `apparmor-utils`:
```
# apk add apparmor-utils
# aa-status
```
## Cmdline
There are a lot of kernel settings which can be passed to the command line. [https://madaidans-insecurities.github.io/guides/linux-hardening.html#kernel](Madadans-insecurity's page) describes each of their function and how they improve security of the system so lets add them to `/etc/kernel-hooks/secureboot.conf`:
After reconfiguring `kernel-hooks` try to reboot and it should boot. Although there are more options that might make the system more secure, these most of the time come with a big performance hit so this should do for now.
