  • It’s been a while for me (I don’t upgrade things that work and I try to buy things that last a long time…)

    But, Hotel Mode might still be a thing, and it might bypass some “smart” stuff on the TV

    I used that to make my TV start on the correct external HDMI port for my MythTV instance running on Arch Linux (btw) with dual TV tuners in.

    The TV is rarely used to watch live TV and it’s certainly not connected to any networking.

    Just another approach that I’ve not seen mentioned here



  • It’s keeping the drawings / spreadsheets / etc. up to date, to know what changes are required, that I’m thinking about.

    With multiple switches, VLANs, subnets, etc and I want to add an IoT device somewhere physically convenient, then maybe I now need to trunk the IoT VLAN through multiple devices from the Wifi AP PoE switch, update firewall rules, because this is the 1st device on that physical segment, etc… and then update the drawings afterwards.

    Now that’s worth automating.

    I’m looking for a map, not a calculator.








  • Consider your perfect settings as the part you want to keep (as well as all your documents etc, of course), but the OS will change.

    Tomorrow you’ll do an update and 2 applications and 10 libraries are now newer… so you probably don’t want to store a “golden image” for too long without redoing it to consider all the updates.

    Now… with that situation in mind, it’s generally easier to just do a clean install of the distro and reapply your settings.

    So, depending on what you’ve setup, installed, tweaked & configured, saving that can be done with config files in /etc and /home and maybe a 1-liner for applications to install.

    That will be smaller and more easily reproducable on all your hardware (and maybe some VMs)

    How you do that depends on what you’ve changed and your skills… maybe bash, maybe ansible, maybe just copying files - whatever makes sense to you.
