I just upgraded from 1.4-epa2 to 1.4-epa3
I noticed on reboot that even though
```set system option kernel disable-mitigations```
was set, that it hadn't been applied.
My fix was to disable it, commit, enable it, commit and then reboot.
I expect maybe there needs to be a check when the config is copied over during the new image install, that looks for this statement and then applies the setting to grub.
This is a very very minor bug.
