What is the most difficult problem that you have fixed in linux?

Used to be messing with kernel arguments and installing/tweaking boot parameters. That was until Grub broke, I learned systemd-boot and chrooting into the system via live USB

Now if I break anything it’s just a matter of “sigh, let me get the USB and type a few commands”

Some of the crap I had to do back in the late 00s to get wifi, sleep and power management even barely working on some machines felt like the hardest thing at the time. I wonder how I’d fare with those issues today, 17 years later, knowing quite a bit more about the underlying OS and working with the OS daily… I don’t know that I’d qualify that as difficult more than it was extremely tedious and a bunch of trial and error of configuration options I didn’t know anything about.

If we’re talking about modern day… not so much honestly. btrfs snapshots saved my ass a couple of times, the rare issue I encounter I just rollback and wait for an upstream fix, and the rest I typically ignore or use something else. Everything tends to run quite smooth for me as a general rule, though.

My first home server would get lost on the network every week, at different times and without any apparent reason. I performed hard resets by unplugging and plugging it back in.

After several months, I decided to connect a screen to it, and I initially thought it had hung up, but it hadn’t. After some investigation, I discovered that every time my router obtained a new dynamic IP address, the server lost its network connection, requiring a reset. I wrote a script to check the network connection every minute, and if it’s lost again, it will be reset.
