So, just made my morningly update, with new kernel, yay. Unfortunately the reboot brings me to a violet screen with only one option available (instead of 4): boot to UEFI. Gone are boot into eos, boot into eos backup and boot into btrfs snapshot (from btrfs-grubd). Well… and now? Data is all there, I even managed to update the live environment of cassini (which gets more and more outdated, nothing an update keyring and pacman -Syu cannot solve, but nevertheless…) to get my keepass running and open so I can login here. Reinstall grub? Do something else? I am quite lost currently…
So, I have at least a tiny clue what has happened:
I have two systems currently installed, one are the leftovers of my Manjaro system in which I boot via BIOS selection, the other one is EOS.

And when I do look no into my crub-cfg it looks… wrong. Because there is Manjaro stuff in it which was never meant to be, never run os-prober or something similar:

Well… what happened here? How do I get to my old Grub? And how to avoid future occurrences?
Hello, it seems your grub.cfg got messed up by the update. You can try to repair the GRUB by arch-chroot to your currently installed EOS system.
Will try to do so. Btw have I posted the wrong grub.cfg above, this was the old one from Manjaro, the dorrect one is this one:

But does not matter much, heh? Both a wrong.
While I was trying the archroot thingy some questions arose, due to me being on BtrFS instead of ext4.
To mount what I need for archroot I will do the following:
sudo mount /dev/nvme0n1p2 /mnt
sudo mount /dev/nvme0n1p1 /mnt/boot/efi
Or do I have to mount the rest of the BtrFS filesystems also?
Another question: Can I somehow restore grub.cfg from my auto-generated snapshots (via snapper and pacman hook)?
My fstab looks like this:
UUID=68E1-1935 /boot/efi vfat defaults,noatime 0 2
UUID=ab5aa1ba-94e9-4c10-8d38-d7f63c007d9a / btrfs subvol=/@,defaults,noatime,compress=zstd 0 0
UUID=ab5aa1ba-94e9-4c10-8d38-d7f63c007d9a /home btrfs subvol=/@home,defaults,noatime,compress=zstd 0 0
UUID=ab5aa1ba-94e9-4c10-8d38-d7f63c007d9a /var/cache btrfs subvol=/@cache,defaults,noatime,compress=zstd 0 0
UUID=ab5aa1ba-94e9-4c10-8d38-d7f63c007d9a /var/log btrfs subvol=/@log,defaults,noatime,compress=zstd 0 0
#UUID=ab5aa1ba-94e9-4c10-8d38-d7f63c007d9a /swap btrfs subvol=/@swap,defaults,noatime 0 0
#/swap/swapfile swap swap defaults 0 0
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
And sorry to ask everything twice and doublecheck, don’t want to brick my system any further than it is allready is…
For this, the best would be @dalto .
You are more than right:
Will do so!
Unfortunately it ain’t working:
[liveuser@eos-2023.05.28 system]$ sudo mount /dev/nvme0n1p2 /mnt -o subvol=@
[liveuser@eos-2023.05.28 system]$ sudo mount /dev/nvme0n1p1 /mnt/boot/efi
mount: /mnt/boot/efi: unknown filesystem type 'vfat'.
dmesg(1) may have more information after failed mount system call.
[liveuser@eos-2023.05.28 system]$
That is interesting.
What does sudo modprobe vfat return?
Don’t know and cannot test - I opted for the brute force solution - reinstall whole system. I need it up and running. Got rid of the old Manjaro installation on the way, and will ask further questions regarding BtrFS in “the” BtrFS topic. Thanks to both of you, this thingy here can drop down…
