I can't make a GRUB config
A few weeks ago, I accidentally updated my kernel, and out of nowhere I got these strange pixelated lines all over my screen. So, I decided to try and use the linux-lts kernel. But, when I tried to chroot into my root directory run
grub-mkconfig /dev/sda
I got
/usr/bin/grub-probe: error: cannot find a device for / (is /dev mounted?)
I am running 32 bit Void.

Why are you usingchroot
? Are you trying to do this from a recovery disk/live CD, or the system itself?

Generally speaking, before chrooting into a dir, mount bind /dev and /sys and mount -t proc the /proc. See the archlinux wiki wiki.archlinux.org/index.php/chroot

The Supergrub utility can boot an installation without a lot of trouble. Then you can fix your bootloader from inside the running distribution.
Supergrub
There is also the excellent SysrescueCD with more features except with more of a learning curve.

mount --bind /proc /mnt/sysimage/proc
mount --bind /dev /mnt/sysimage/dev
mount --bind /sys /mnt/sysimage/sys
mount --bind /run /mnt/sysimage/run
Then chroot /mnt/sysimage
, regenerate grub.cfg and initramfs.

Before you chroot into your root partition ("chroot /mnt/sysimage/" for example), you need to mount some system directories first.
mount --bind /proc /mnt/sysimage/proc
mount --bind /dev /mnt/sysimage/dev
mount --bind /sys /mnt/sysimage/sys
mount --bind /run /mnt/sysimage/run
Then chroot /mnt/sysimage
, regenerate grub.cfg and initramfs.
