  • I just realized I sound way too paranoid but it’s an interesting question

    Nope. Not paranoid enough. If school/work requires such software, that goes onto a separate device only for those purposes, which will then be considered untrustworthy environment like any public computer.

    Although perhaps in a sense it is paranoid compared to what others do. Recently I’ve had to get something printed without having own printer. I’ve found out people have no problem logging into their Google or Microsoft account on public PCs.
    I brought the PDF on a CD.
    There’s a certain small chance that something malicious could be written to a USB, and I don’t know about all the possible vulnerabilities. If mounted, perhaps the automatic media thumbnail generator could be exploited. That is probably paranoid, worrying about random software installed on your own computer is certainly not.














  • Arch. After every update I check what broke. And then discover things I forgot to check.

    I am still not sure if it’s already safe to upgrade VirtualBox and iio-sensor-proxy, but I am too lazy to just downgrade them yet again.

    So I just…

    IgnorePkg   = iio-sensor-proxy # Issues in Wayland after suspend
    IgnorePkg   = virtualbox virtualbox-host-modules-lts virtualbox-host-dkms virtualbox-guest-iso # Segfault in 7.2.x, reverted to 7.1.8 - see sys-management-log.txt entry 2025-08-29
    

    If you’re curious about the log entries:

    2025-07-06:
            downgraded iio-sensor-proxy to 3.6-1 as 3.7 caused issues after suspending
            added iio-sensor-proxy to IgnorePkg in /etc/pacman.conf
    
    2025-08-29:
            downgraded virtualbox packages to 7.1.8 as 7.2.x was broken (segfault)
            installed linux-lts-headers as the downgraded virtualbox suddenly wanted that
            removed and reinstalled related packages a couple of times (virtualbox-host-modules-lts, virtualbox-host-modules-arch, virtualbox-host-dkms), as well as switching between linux-lts and linux. Hopefully that didn't create any brand new funny business.
            I want to die
            added IgnorePkg   = virtualbox virtualbox-host-modules-lts virtualbox-host-dkms virtualbox-guest-iso to /etc/pacman.conf
    

    I recommend writing some documentation about your system. My Manjaro install became a total unknown mess after a while. I know I had to create some symlinks at some point to fix something, something something custom “XDG_CONFIG_HOME” dir with separate theme to un-break Cisco Packet Tracer on dark theme, edited startup script for Packet Tracer.
    On one Ubuntu VM I edited a bunch of config files that I didn’t remember so it was just don’t touch it while it works.

    But hey, I feel better after knowing that during high school our internet was down for weeks because something broke on main proxy server and nobody had documentation for the 2 decades old backup server, including the password, so it just ended up running in a “don’t touch it” mode, except that it also limited download speed on unknown PCs (based on MAC) to something like 32Kbps, which after 20 years meant nearly any PC so the solution was to copy MACs from basically ewaste.

    Anyway… write documentation for what you do.
