Yes, I’ve been affected by the grub crap several times.
Been using arch and endeavour for about 5 years now, only ever had boot issues caused by Nvidia drivers. Outside of grub that is.
My backup pc had the most issues with updates, and it doesn’t have a dedicated GPU. I wouldn’t update it for a few weeks or a month+, update, fail to boot, rollback, try again in a few weeks and it would work.
The final straw was when I was working abroad with bad internet, and had to weigh whether -S or -Syu is more likely to cause a failure.
Interesting. How long ago was this? I use arch daily as my main driver, but also run it on a vps, a laptop, and a raspberry pi (arm distro). Other than grub, I can’t recall the last time upgrading caused an issue.
The last time was 6+ months ago because I stopped using Arch. It happened from time to time on both of my machines, but it had a lot higher chance to happen on that particular pc than on my ThinkPad. I’m guessing it was more frequent because the main one was getting updated multiple times a week.
There was one good warning sign though: if I needed to -Syyu, something was most likely going to go wrong with the update.
