  • If a debian based distro there’s several ways to copy your package choices from one machine to another, the likes of using dpkg --get-selections and using that output on the new machine with --set-selections, but probably the easiest way is to use apt-clone, which streamlines that process to install the same packages on the new machine.

    As for your firefox and desktop packages, they’ll be saved in /home/username (usually in .hidden dirs) - so just copy all of that over.

    Alternatively, use an image cloner like clonezilla to make an exact disk copy and install that.

    Or run your machine as a vm inside Proxmox or another hypervisor. That way you can have instant snapshots before you do risky things, as well as multiple scheduled entire-machine backups.

    Or ansible (which I do a lot of), which can set whatever packages and copy your golden-image files over as you want. (But keeping those up to date requires a little thought)



  • OS update fuss level is hugely dependant on distro though.

    EL and rebuilds? Full new machine and copy services over (or if paying RHEL, use their migrator which can have mixed results). Agree, huge fuss.

    Debian/ubuntu? Dist-upgrade, normally safe and much quicker.

    Plus a bunch of rolling release distros that just keep up to date (but will occasionally add breaking changes that you might not be ready for)

    Can’t so easily get around hardware issues, so build cattle that can be easily redeployed or scaled. Doesn’t fit all situations though.










  • It’s a lot of work, but if you’re feeling tired or overhwelmed and thinking negative thoughts about these releases - then don’t. It’s a good thing.

    These are bugs that already exist and, in some cases, are almost certainly being actively exploited by criminals and government-backed organistions both.

    Whilst we might ask that some are a little more responsible with their disclosures, overall this is a massive boost to computer security once we get over this hill of information.
