  • I haven’t tried any yet, but my understanding is that recently there’s been a trend of immutable Linux distros, where the root filesystem is immutable (read-only). Instead of directly changing stuff in /etc, installing apps, etc, you instead update some sort of config that says exactly how to set up the system, and rerun a script that rebuilds the root.

    System updates are atomic - either the whole update is completed, or the whole update is rolled back. If the system breaks, you can revert back to an old config file and restore it to exactly the same state as it was before.

    It’s still not very common - the majority of Linux systems aren’t doing this.









  • you need at least two NICs to properly setup a firewall.

    I’m not sure I’d recommend it, but two (or more) VLANs on a single NIC would work fine too. This setup is usually referred to as “router on a stick”

    I’m not sure about other OSes or Linux distros, but it’s easy to add multiple VLANs on Debian. You load the 8021q kernel module, then add interfaces suffixed with the VLAN ID (e.g. if your NIC is ens3, you’d add ens3.10 to /etc/network/interfaces for VLAN 10). You’d also need to make sure the switch port is configured to allow VLAN10.

    Older NICs lead to regular crashes and/or slow network speeds.

    but the ones you’re suggesting (I350-T2 and -T4) are 12 years old.
