I've read a bit about systemd-sysupdate and it seemed like something we might want to have for our mobile devices.

Then I was wondering whether any distribution already uses it on mobile devices.

systemd-sysupdate atomically updates the host OS, container images, portable service images or other sources, based on the transfer configuration files described in sysupdate.d(5).

Most package managers already have something like this, or can be configured to work in the same way.

This is also a relatively new systemd addition. Let it settle for a while. Conservative distros like Debian Stable don't have it yet anyhow.

@erebion @postmarketOS is working on immutable variant called duranium that seems to use systemd-sysupdate. Here is the design document for more details:
