Public bug reported:
Remounting log mounts in Ubuntu core are failing on arm64 builds due to missing
CONFIG_NLS_ASCII in the arm64 kernel build options.
This option is enabled on the other kernel builds but somehow was overlooked on
arm64 appears to affect our ability to access logs via journalctl with data
from prior to restart because certain mounts are failing.
Other Raspberry Pi kernel builds, such as the armhf build, have the option
enabled and so do not encounter the mount error.
The kernel option that needs to be turned on to resolve this is
CONFIG_NLS_ASCII. It needs to be set to either 'm' or 'y'. Most of the other
chips have it set to 'y', keeping it built-in.
