Title:
  Mantic autoinstall.yaml fails on late commands

Status in subiquity:
  In Progress

Bug description:
  Description:
  Late commands in the autoinstall.yaml file worked for 23.04 installer. "As Far As We Know": Nothing has been  changed for that process between 23.04 and 23.10. I have verified that from the example yaml files in /snap/ubuntu-desktop-installer/1[0-9][0-9][0-9]/usr/share/doc/*/examples/

  Yet the autoinstall scripts we have working for 23.04, fail on late
  commands for 23.10.They seem to work for internal bash commands, but
  not for starting installer bash scripts used for installing packages
  and other environment setup.

  This worked for 23.04, no longer with 23.10 or 23.04.1.

  RE: https://ubuntuforums.org/showthread.php?t=2491776

  Expected Behavior:
  Late Command to run custom late-install scripts works.

  Steps to Reproduce:

  Use this yaml, or sililar file --+v
  ###
  version: 1
    refresh-installer:
            update: yes
    keyboard:
      layout: se
    locale: en_US.UTF-8
    timezone: Europe/Stockholm
    identity:
      hostname: unassigned-hostname
      username: ubuntu
      password: ubuntu (not the real one)
    source:
      search_drivers: true
      id: ubuntu-desktop-minimal
    storage:
      layout:
        name: direct
    updates: all
    late-commands:
      - mkdir /target/opt/packages
      - mkdir /target/opt/scripts
      - cp -r /cdrom/packages /target/opt
      - cp -r /cdrom/nocloud/scripts /target/opt
      - curtin in-target -- bash /opt/scripts/post-install1.sh
      - curtin in-target -- bash /opt/scripts/post-install2.sh
      - curtin in-target -- bash /opt/scripts/post-install3.sh
  ###
  Use logger in those scripts to log that they were called an ran to verify that it is working...

  If no log entries, then it failed.

  *** The scripts and everything is getting copied over. The scripts are not running
    All those scripts can run manually after the install. Just not from within the installer.

  Alternate work-arounds:
   - We have tried adding the full path /usr/bin/bash to the late command,. That also fails...
   - We have tried chmod'ing the scripts to make them executable and calling them directly. That also fails

  Has something changed?

  The Noble repo's are up now. We start testing that as soon as the
  packages are really ready for that. Right now they are still the
  Mantic packages, so this release is also affected.
