11.3. Performing manual updates from an installed operating system

Prerequisites

• A booted system using bootc.

Procedure

• Disable the timer of a container build.

  • By running the systemctl mask command:

    $ systemctl mask bootc-fetch-apply-updates.timer

  • By modifying the systemd timer file. Use systemd "drop-ins" to override the timer. In the following example, updates are scheduled for once a week.

    1. Create an updates.conf file with the following content:

       [Timer]
       # Clear previous timers
       OnBootSec= OnBootSec=1w OnUnitInactiveSec=1w

    2. Add you file to the directory that you created:

       $ mkdir -p /usr/lib/systemd/system/bootc-fetch-apply-updates.timer.d
       $ cp updates.conf /usr/lib/systemd/system/bootc-fetch-apply-updates.timer.d

Prerequisites

• A booted system using bootc.

Procedure

• Run the following command:

  $ bootc upgrade [--apply]

  The apply argument is optional and you can use it when you want to automatically take actions, such as rebooting if the system has changed.
