From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Silverblue: Run ostree updates at shutdown? (lemmy.ca)

Fellow Fedora Immutable users, have any of you automated your system updates to occur at shutdown? If so, do you find it makes a practical difference?

I'm thinking of doing the same with Tony Walker's silverblue-update service.

I shutdown most of my machines daily, and that often means getting an updated image shortly after startup the next day and being forced to reboot or nearly always remain one day behind in updates. By checking for updates again at shutdown, this should help ensure I've always got the latest daily image at boot. Thoughts?

I run the built-in automatic rpm-ostree upgrade service every 6 hours.

If you think that's too inefficient, maybe read the docs for shutdown.target and see if you can use that to run an upgrade service before shutdown?

I'm not too experienced with that part of systemd but it seems like it could be a "proper" way to run things on shutdown?

Thanks, yeah I've found a few articles already on running scripts at shutdown...something like this should do it (using Tony Walker's update script), though I've not tested it yet:

/etc/systemd/system/silverblue-update-at-shutdown.service:

[Unit]
Description=Fedora Silverblue Update at Shutdown 
ConditionPathExists=/run/ostree-booted
DefaultDependencies=no
Before=shutdown.target

[Service]
Type=oneshot
ExecStart=/usr/local/bin/silverblue-update
TimeoutStartSec=0

[Install]
WantedBy=shutdown.target
