Systemd is getting system updater

khem · March 31, 2022, 4:41pm

Reading through release notes of upcoming 251 systemd release, there are bunch of interesting features. One caught my eye was systemd-sysupdate

A new systemd-sysupdate component has been added that automatically
discovers, downloads, and installs A/B-style updates for the host
installation itself, or container images, portable service images,
and other assets. See the new systemd-sysupdate man page for updates.

Details list of changes are here

I wonder if this will be a good option for system updates in future.
