Yep exactly! Setting up a raspberry pi low-performance computing cluster with secondary usb nics, going slowly insane trying to figure out why the vlan interfaces wouldn’t work when their base interfaces worked just fine, and going down all of the wrong rabbit holes along the way.

ifupdown2 has a 15-character interface name limit, and the systemd predictable interface naming system uses the mac address for usb nics (giving them a 15-character name), so if you try to create a vlan subinterface of a usb nic using the standard interface.vlan naming scheme on a systemd host, it will fail, and you’ll have to set up systemd network link files to rename the base interfaces to something shorter.
mlfh@lemmy.sdf.orgto Linux@lemmy.ml•Linux: How to use energy better in general by fine-tuning laptop battery?3·2 months agoThe ups has data output to my firewall/router via usb, which the baremetal servers all connect to via apcupsd. When the ups loses or regains AC power, it broadcasts a message to all of them and they’re each scripted to act accordingly: laptops run on their own batteries, vms migrate over to laptops, non-vital hardware shuts down, etc.

mlfh@lemmy.sdf.orgto Linux@lemmy.ml•Atomic Linux Distros: What Barriers Stand Between You and Making the Switch?4·3 months agoI switched a workstation to Secureblue for the very specific security priorities targeted by that project, but I think for the majority of users, the main reason for not switching to atomic is one you mentioned: why fix what isn’t broken? The main selling point promoted to potential new users seems to be that updates don’t break anything, but I can’t remember a single time since Debian Sarge that an update broke anything for me, and I actually find the rpm-ostree package layering and updating process to be far more of a headache than otherwise.
Unless it’s prepackaged like a steam deck, moving from the traditional way of doing things to atomic is a major change. Like any major change, people need a good reason to make it, and I think right now the only compelling ones are either hyper-specific (switching to okd and needing to build it on coreos, wanting to move to a specific atomic project, etc.), or just general curiosity.
Band of Brothers. The intro is so long, but feels like an important part of the whole experience.
Four Weddings and a Funeral is a movie I adore entirely for the side characters, and pretty much ignore the two main characters and storyline completely.
The main friend group feels so real and alive and lovely, they’re charming and funny, and watching them be friends at their weddings and funeral feels like optimistic slice-of-life escapism. And beyond that, pretty much every other side character is memorable and funny and a joy to watch, especially Rowan Atkinson as the anxious priest. Great movie, 10/10, can’t remember the main characters at all.
