System-wide default LANG setting in locale.conf

[yuvadm]

While en_US.UTF-8 is the only default locale installed system-wide, it is not configured to be used anywhere explicitly, leaving it up to the user to decide where to set LANG=en_US.UTF-8 in their environment when required.

It might be useful to set this system-wide in advance via /etc/locale.conf, although this might have adverse effects in other scenarios.

A user who wishes to workaround this in the meantime can use debops.resources to set, for example:

resources__host_files:
  - dest: '/etc/locale.conf'
    mode: '0644'
    content: |
      LANG=en_US.UTF-8
