  • I’ve got raid 6 at the base level and LVM for partitioning and ext4 filesystem for a k8s setup. Based on this, btrfs doesn’t provide me with any advantages that I don’t already have at a lower level.

    Additionaly, for my system, btrfs uses more bits per file or something such that I was running out of disk space vs ext4. Yeah, I can go buy more disks, but I like to think that I’m running at peak efficiency, using all the bits, with no waste.










  • Yes. It’s the “put a copy somewhere else” that I’m trying to solve for without a lot of cost and effort. So far, having a remote copy at a relative’s is good for being off site and cost, but the amount of time to support it has been less than ideal since the Pi will sometimes become unresponsive for unknown reasons and getting the family member to reboot it “is too hard”.



  • Take some time and really analyze your threat model. There are different solutions for each of them. For example, protecting against a friend swiping the drives may be as simple as LUKS on the drive and a USB key with the unlock keys. Another poster suggested leaving the backup computer wide open but encrypting the files that you back up with symmetric or asymmetric, based on your needs. If you’re hiding it from the government, check your local laws. You may be guilty until proven innocent in which case you need “plausible deniability” of what’s on the drive. That’s a different solution. Are you dealing with a well funded nation-state adversary? Maybe keying in the password isn’t such a bad idea.

    I’m using LUKS with mandos on a raspberry PI. I back up to a Pi at a friend’s house over TailScale where the disk is wide open, but Duplicity will encrypt the backup file. My threat model is a run of the mill thief swiping the computers and script kiddies hacking in.



  • I had one from Sony a long time ago. It even had a cable you could attach between two of 'em (600 CDs!) so that it could seamlessly start playing another track while loading the next song. I dropped it during a move and the next time I opened the door, it spit gears at me. I had intended to fix it some day, but started watching Hoarders and decided it wasn’t worth it.




  • It depends on what you do with Docker. Podman can replace many of the core docker features, but does not ship with a Docker Desktop app (there may be one available). Also, last I checked, there were differences in the docker build command.

    That being said, I’m using podman at home and work, doing development things and building images must fine. My final images are built in a pipeline with actual Docker, though.

    I jumped ship from Docker (like the metaphor?) when they started clamping down on unregistered users and changed the corporate license. It’s my personal middle finger to them.


  • I’m using Kubernetes and many of the apps that I use require environment variables to pass secrets. Another option is the pod definition, which is viewable by anybody with read privileges to K8s. Secrets are great to secure it on the K8s side, but the application either needs to read the secret from a file or you build your own helm chart with a shell front end to create app config files on the fly. I’m sure there are other options, but there’s no “one size fits all” type solution.

    The real issue here is that the app is happy to expose it’s environment variables with no consideration given to the fact that it may contain data that can be misused by bad actors. It’s security 101 to not expose any more than the user needs to see which is why stack dumps are disabled on production implementations.
