Triggering offline update next reboot with immediatly rebooting

[siepkes]

In order to update workstations used (among things) by non-technical end-users I need to download and install updates unattended. I'm currently using the following script with a systemd timer:

#!/usr/bin/env ksh93

NM_METERED=$(busctl -j get-property org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager Metered | jq .data)
NM_METERED_NO="2"
NM_METERED_GUESS_NO="4"

if [ "${NM_METERED}" == "${NM_METERED_NO}" ] || [ "${NM_METERED}" == "${NM_METERED_GUESS_NO}" ]; then
  dnf5 upgrade --offline -y && \
  DNF_SYSTEM_UPGRADE_NO_REBOOT=1 dnf5 offline reboot -y
else
  echo "Metered Connection status: '${NM_METERED}'. Not checking for updates."
fi

So I'm using DNF_SYSTEM_UPGRADE_NO_REBOOT with dnf5 offline reboot -y to prevent the system from rebooting immediately but to wait for the user to manually reboot the system. However this flag seems to be undocumented for use with dnf5 offline reboot -y and I'm somewhat weary this behavior might change.

So I was wondering if there is any chance there would ever be a flag added to dnf5 offline to install the updates without doing a reboot immediately?
