Thanks Valdis. I checked /lib/modules directory. It had a lot of subdirectories - one for each kernel build I guess, each one around 4GB. I have removed some of the older one's with "rm" cmd. I hope it doesn't break grub. Grub doesn't care, it only cares that the bzImage/vmlinuz and (if needed) initramfs that you listed in the grub config file are there. (Actually, it doesn't actually *check* until you try to boot a kernel and it can't find them there, at which point it will tell you...)
The kernel you boot will care if one of the directories you nuked from /lib/modules was for the version of the kernel you booted. In other words, if you did an rm -r /lib/modules/4.19.9-rc12 you may as well toss any 4.19.9-rc12 files in /boot and the Grub menu.
However, the initramfs *should* have included any modules needed to get your root filesystem mounted, so even if you removed the directory for a given 'uname -r', you should still be able to boot single-user.
