Out of curiosity: Which operating system(s) can you shutdown while the kernel is being overwritten? I wouldn't imagine that as a limitation of Arch Linux specifically.

[-] technocat@lemmy.world 24 points 4 months ago

I think fedora would survive this abuse. It doesn't replace when you install kernels, but instead adds it.

[-] TxzK@lemmy.zip 9 points 4 months ago

Also Fedora ships 3 kernels by default. If one breaks, maybe the others will keep working.

[-] zloubida@lemmy.world 5 points 4 months ago

With Manjaro you choose how much kernels you want.

[-] aniki@lemmy.zip 13 points 4 months ago

Arch let's you install kernels till /boot is full...

[-] RootAccess@lemmynsfw.com 1 points 4 months ago

Yes. I have it set up this way. I forgot it wasn't the default. For the amount of headache it would solve, I wonder if the Arch team has a specific reason for not keeping a number of previous kernels by default.

[-] jonne@infosec.pub 5 points 4 months ago

Ubuntu (and probably Debian too) will keep an old kernel in your grub list so you can boot off that one if needed.

Arch Linux with 2 kernels ;)

[-] palordrolap@kbin.run 11 points 4 months ago

Mint definitely keeps a couple of previous kernels around, so that might be a Debian and Ubuntu thing too.

That said, there's always going to be a critical point of failure that a power loss could cause things to break, no matter your OS or distro.

Writing the bootloader or updating a partition table for example.

Anything running on a copy-on-write filesystem can trivially rollback changes using a rescue partition.

I also expect most immutable distros would be able to be especially good at tanking this.

[-] leftzero@lemmynsfw.com 2 points 4 months ago

I assume NixOs would just let you load a previous working configuration if the current one got corrupted (though in this case it probably could simply rebuild the current one).

Windows

Goes back to a previous restore point

[-] RootAccess@lemmynsfw.com 1 points 4 months ago

I haven't used Windows since Win7 - Is it possible nowadays to immediately cancel a kernel-level upgrade (say, Win7 to Win8) and have it gracefully stop and then boot into the pre-upgrade environment? If so, then Windows has come a long way. We use to be careful breathing-too-loudly around Windows computers during the upgrade process. Microsoft must be getting better.
