Hello,
Yesterday, I updated my system for the first time in 2 or 3 weeks, but it failed. I already looked up other posts, but the solutions were quite different, and I don't want to do more damage.
It's probably important to know that I'm using Arch since March, I'm using BTRFS. But didn't create any subvolumes during the installation. I did it afterwards for @root and @home and everything works fine. But the thing is, I did it like 3 weeks ago and the aforementioned system update might be the first one since (but I'm not sure), so I guess that the problem might have something to do with it.
I get the following error while trying to boot
linux-zen
(my default):
while trying to use
linux
or
linux-lts
instead, get the following error:
ERROR: Boot device mounted successfully, but /sbin/init does not exist.
Bailing out, you are on your own. Good luck.
sh: can't access tty: job control turned off
[rootfs ~]
Using
linux-zen
and entering
systemctl status boot-efi.mount
the output is:
My /etc/fstab is:

My grub.cgf is as following:

I don't have an Arch live USB, but I have EndeavourOS on a different drive, so I can boot into it to perform maintenance.
I would really appreciate any help!

I ran
uname -a
and it says
Linux NexusArch 6.10.7-zen1-1-zen
while
pacman -Qi linux-zen
says
6.10.10.zen1-1
running
pacman -S linux-zen
seems to reinstall the kernel, but after rebooting, it still is on 6.10.7-zen-1-1
If I understood it correctly, it may be related to the problem. It does not seem to use the newer kernel.
Any help, please?

In the post before, I ran these commands while booting into arch.
Now, I chrooted into Arch (because /boot/efi was not mounted) and:
mount /dev/nvme0n1p3 /mnt -o subvol=@
mount /dev/nvme0n1p1 /mnt/boot/efit
arch-chroot /mnt
pacman -S linux linux-zen linux-lts base linux-firmware
grub-mkconfig -o /boot/grub/grub.cfg
After rebooting, nothing changed. I'm still on 6.10.7-zen1-1-zen. I don't even know if this is really the problem here.

Btw., the grub output says that the timeshift-btrfs snapshots are found, but none of them show in grub while booting.

Now I know where the problem is!
On my disk, I have the subvolumes
@
@home
with @ as my new root.
Since I migrated to subvolumes, I still have /boot in my old root where @ is located. But I have another /boot in my @ directory. When I update, it updates @/boot, while my /boot in my old root is outdated.
I'm glad that I didn't clean up yet. So I copied the contents of @/boot to /boot, and now I can boot into Arch again (and see my timeshift backups in grub while booting!).
It works, but it is pretty messed up
Did configure fstab wrong?

Does the section with /boot/efi has to look different?
My guess would be
/dev/nvme0n1p1 /boot/efi vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro subvol=/@/boot/efi 0 2

You need to run the grub-install command again so that GRUB looks for grub.cfg in the @ subvolume.
EDIT: and please edit posts rather than add new ones if nobody has replied (as I have done in this post), it makes the thread much more readable.
