Systemd is both in a lot more large distros than just Fedora, RHEL and has limited viable alternatives (OpenRC as a partial replacement, no others I can think of that come close). While it has its issues particularly with the extra bundled services of mixed quality, SystemD is generally a flexible and suitable option for service management on Linux.

Not to mention how inflammatory the parent comment is.

GrapheneOS only publishes updates for devices with active security updates. Your device is EOL and therefore won’t receive any further mainline updates. It still will receive extended support from the Android 14 legacy branch with whatever security patches arrive in upstream AOSP, but unlikely to see device-specific patches nor firmware patches. Your device isn’t getting the same care and attention that active devices are receiving nor will it receive any future versions of Android through GrapheneOS.

For what it’s worth, I do think OCIS is worthy of switching to if you don’t make use of all of the various apps Nextcloud can do. OCIS can hook into an online office provider, but doesn’t do much more than just the cloud storage as of right now.

That said, the cloud storage and UX performance is night and day between Nextcloud/Owncloud and OCIS. If you’re using a S3 provider as a storage backend, then you only need to ensure backups for the S3 objects and the small metadata volume the OCIS container needs in order to ensure file integrity.

Another thing to note about OCIS: it provides no at-rest encryption module unlike Nextcloud. If that’s important to your use case, either stick with Nextcloud or you will need to figure out how to roll your own.

I know that OCIS does intend to bring more features into the stack eventually (CalDAV, CardDAV, etc.). As it stands currently though, OCIS isn’t a behemoth that Nextcloud/Owncloud are, and the architecture, maintenance is more straightforward overall.

As for open-source: OCIS released and has still remained under Apache 2.0 for its entire lifespan thus far. If you don’t trust Owncloud over the drama that created Nextcloud, then I guess remain wary? Otherwise OCIS looks fine to use.
