okay so bestie, pull up a chair, because this one is from the Kernel Interfaces Manual and it's honestly shorter than my attention span but we're gonna make it iconic anyway 🎀

✨ NAME ✨

ld — the logical disk driver. that's it. that's the name. main character energy, no notes 💅

🦋 SYNOPSIS 🦋

so here's like, every way you can attach this thing. no cap, here's the whole list:

look at all those parents, it's giving "everyone wants a piece of me" 😭💖

🌸 DESCRIPTION 🌸

the ld driver is out here providing support for simple block devices, and those are usually presented by a disk array controller. lowkey humble, highkey essential. that's the whole vibe check bestie 🫶

🎀 FILES 🎀

  • /dev/ldup — block mode disk unit u, partition p 💖
  • /dev/rldup — raw mode disk unit u, partition p 🔥

(yes the u and the p are placeholders, don't come for me, they're literally in the original, iykyk ✨)

🧚 SEE ALSO 🧚

go read these besties next, they're all part of the friend group:

aac(4), amr(4), cac(4), icp(4), intro(4), iop(4), mlx(4), nvme(4), sdmmc(4), twa(4), twe(4), virtio(4)

⭐ HISTORY ⭐

the ld driver first appeared in NetBSD 1.5.3. a genuine vintage icon, we stan an elder 👑

💀 BUGS 💀

okay listen, this is the important part so pay attention:

the capacity and geometry of units as accessed through the ld driver may be different than when accessed through some other medium (e.g. SCSI).

not me warning you about this — it's literally in the manual fr fr. don't be surprised when the numbers don't match, it's giving "it's not a bug it's a feature" but it IS a bug 🙈💀

and that's the whole page bestie, you ate that 💅✨
