✨ SYNOPSIS ✨

pseudo-device rd [count]

🦋 DESCRIPTION 🦋

The rd driver enables use of system or user memory as a disk. that's the whole glow-up: memory becomes a disk. ✨

Memory for the disk must be allocated and initialized inside the kernel image at build-time using the rdsetroot tool. periodt. that's a build-time thing, and rdsetroot is the tool named right there. 💅
