Cake day: November 4th, 2023

  • I accidentally overwrote /etc/passwd once and I allowed /boot to run out of space during a kernal update and I created a local user with the same user that was also on the realm/domain that I had joined and various bash script issues.
    Some stuff I’ve had to fix that someone else did:

    • named a file rm -rf
    • rm -rf /bin instead of ./bin – Also the fact that they had sudo was crazy and also I guess this was the second time
    • chmod -R 777 /
    • Various software bugs running swap out of space or hitting the inode limit by creating files over and over again with a timestamp in the filename and having to remove all of them because there was no backup to the OS
    • Someone disabled SELinux because something wasn’t working but didn’t tell anyone – ugh
    • Compiled java because they googled some issue and followed some old tutorial without understanding anything instead of using alternatives and symlinked the old java from /bin to /home/theiruser/java – had sudo because he was a Windows domain admin.
    • Cybersecurity guy didn’t know what some VMs did so he turned them off and figured he’d find out if/when someone complained. Caused a massive core services outage.
    • Same Cybersecurity guy deleted a bunch of data because he wanted to see how the sysadmins would respond and witness backup restorations. He did not inform anyone.
    • Cybersecurity guy above still has Domain Admin and sudo everywhere. I would have personally removed his privileged access regardless of what ‘CyberSecurity’ management thought but I was leaving for a new job by then anyway so I figured I’d just let them eventually lie in the bed they made.

    There’s more but I don’t want to keep going because it is Sunday and I don’t want to ruin it.







  • Your immutable OS stays stable. For example, running a sudo pacman -Syu with a bunch of stuff from AUR in your Arch container for example will not bring down your OS or otherwise make it unstable. The immutable image you first install has been tested and it is the same image as the testers – same with the upgrades and updates, so long as you don’t overlap the image with rpm-ostree in this case.

    Immutability keeps your OS stable and if something does happen to go wrong, you just roll it back.

    If that isn’t something you need/want then that’s not something you need/want.


  • Yes, though keep in mind containers aren’t like VMs so the hardware isn’t virtualized or anything. The root system and everything in it is still immutable as well. In usage, it doesn’t matter for the container but it isn’t changing the root since what is writable to the container is outside of the root.

    Using containers this way is the way Silverblue was intended to be used for by the user and pretty much any other immutable distro of note.
