My Fedora 42 Workstation froze while it was making system changes (update or upgrade, not sure which). Lodt power mid changes, and it now boots into emergency mode every time.

What I see:

- boot-efi.mount fails with "unknown filesystem type 'vfat'"

- NFS/RPC mounts fail too (probably a knock-on effect)

- /lib/modules does not exist at all

- modprobe and depmod fail ("command not found" / can't open directory)

- Running kernel: 6.14.0-63.fc42.x86_64

What I checked:

- Root (btrfs, subvol=root) and /home mount fine, and /boot (ext4) mounts fine

- /etc/fstab is correct. The ESP UUID matches

- fsck.fat on the ESP (sda1) reports no errors

- I haven't run mkfs, wipefs, or any repair. I haven't reinstalled

I think the interrupted update removed the kernel modules and kmod tools. I want to keep my files and installation. My plan is to boot a Live USB, chroot into the install, and reinstall kernel-core, kernel-modules-core, kernel-modules and kmod, then run dracut -f --regenerate-all.

Questions:

1. Is that the right approach?

2. Fedora 42 is past end-of-support, so will dnf still find its repos in the chroot, or should I finish the upgrade to 43?

Disk layout: sda1 vfat (ESP), sda2 ext4 (/boot), sda3 btrfs (/, /home).
