title: Trying to mount /dev/sda in busybox
body: <p>I'm using Proxmox VM's. Doesn't seem to matter what storage type I choose (scsi, ivirt, or sata), I don't see any block devices (i.e. under <code>/dev</code> or with <code>fdisk</code>) in busybox.</p>
  <p>I used these instructions to get PXE to a busybox prompt:</p>
  <p><a href="https://jootamam.net/howto-initramfs-image.htm" rel="nofollow noreferrer">https://jootamam.net/howto-initramfs-image.htm</a></p>
  <p>If I could see the drive. I could then untar a larger <code>root.fs</code> to it and use <code>busybox</code>/<code>initramfs</code> to <code>switch_exec</code> to <code>sda1</code> (similar to <a href="http://www.espenbraastad.no/posts/centos-7-rootfs-on-tmpfs/" rel="nofollow noreferrer">these instructions</a> for <code>tmpfs</code>).
  But because I can't, I'm limited to untarring to tmpfs/ram.</p>
  <p>Is there a module I need to load?</p>
