I have Artix Linux installed on a VM and tried mounting the boot section of an SD card.
It fails.
$ sudo mount /dev/sda1 /mnt
mount: /mnt: unknown filesystem type 'vfat'.
dmesg(1) may have more information after failed mount system call.
$ modprobe vfat
modprobe: FATAL: Module vfat not found in directory /lib/modules/6.12.4-artix1-1
What to do?
Post pacman -Q | grep ^linux
Looks I had upgraded linux to version 6.12.8 and run into a boot issue.
And since my boot is weird (using coreboot.. I think?)
I had to reinstall my VM in order to solve this problem.
