the rule of thumb here is that you should really just use one browser ad blocker. having multiple will conflict especially regarding anti-adblocker prevention (as uBO will try to hide itself and redirect to a “defused” version of an ad script and whatever other ad blocker you have will think that’s an ad and block it)

not entirely sure how well DNS ad blockers fit into this. there is a chance they could make your ad blocking detectable by blocking a request uBO intentionally lets through (possibly in a modified state), but as far as i’m aware there haven’t been too many issues stemming from combining DNS blockers with uBO and the likes.

DNS blocking is the most unreliable way of blocking youtube ads you can imagine.
you could write a script to OCR your entire screen and click skip ad and it’d be more reliable than DNS blocking

One of the reasons I use containers instead of installing things directly is that i can completely uninstall a service by deleting a single directory (that contains a compose.yml and any necessary volumes) and running a docker/podman system prune -a

or that i can back up everything by backing up a single “containers” dir, which i could have on a subvolume and snapshot if i wanted to

systemd/quadlet on the other hand makes me throw files in /etc (which is where you’re supposed to put them, but ends up resulting in them being tangled together with base system configuration often partially managed by the package manager)

The Solution™ to this is configuration management like ansible or whatnot, which needlessly overcomplicates things for the use cases i need (though they’re still useful for getting a base system “container ready” wrt ssh hardening and such)

tldr: i want my base system to be separated from my services, and systemd integration is the exact wrong tool for this job

the allowed instances list acts as an allowlist, meaning you’d be defederating yourself from the rest of the fediverse (and only federating with the instances you allow).

if that’s what you were going for ofc it’s your right and i sure won’t stop you from doing that, but i feel like you’ve misunderstood what it is.
