Fedora 27 Automatic Updates

I thought I’d write a quick short port on setting up automatic updates on Fedora 27.

$ dnf install dnf-automatic

I am only going to do security updates and have them applied. What you do is up to you. :)

# diff /etc/dnf/automatic.conf /etc/dnf/automatic.conf.orig
5c5
< upgrade_type = security
---
> upgrade_type = default
18c18
< apply_updates = yes
---
> apply_updates = no

What timers do we have right now? (Ah, systemd, let’s replace cron. Sigh.)

$ systemctl list-timers *dnf-*
NEXT                         LEFT       LAST                         PASSED       UNIT                ACTIVATES

1 timers listed.
Pass --all to see loaded but inactive timers, too.

Hmm there are several dnf timers.

root# ls -1 /usr/lib/systemd/system/dnf*.timer
/usr/lib/systemd/system/dnf-automatic-download.timer
/usr/lib/systemd/system/dnf-automatic-install.timer
/usr/lib/systemd/system/dnf-automatic-notifyonly.timer
/usr/lib/systemd/system/dnf-automatic.timer
/usr/lib/systemd/system/dnf-makecache.timer

What does automatic.timer do? Runs the dnf-automatic service.

root# cat /usr/lib/systemd/system/dnf-automatic.service
[Unit]
Description=dnf automatic
# See comment in dnf-makecache.service
ConditionPathExists=!/run/ostree-booted

Type=oneshot
Nice=19
IOSchedulingClass=2
IOSchedulingPriority=7
Environment="ABRT_IGNORE_PYTHON=1"
ExecStart=/usr/bin/dnf-automatic /etc/dnf/automatic.conf --timer

Ok, let’s start the timer.

root# systemctl enable dnf-automatic.timer && systemctl start dnf-automatic.timer
Created symlink /etc/systemd/system/basic.target.wants/dnf-automatic.timer → /usr/lib/systemd/system/dnf-automatic.timer.

So, there you go. Will this computer be more secure now? I hope so. :)
