It instructs the build process +to build a busybox binary that contains *only* the mdev command +and its dependencies. That one will be copied into the initramfs: +the initramfs uses "mdev" and "mdev -s" commands, this is necessary +for coldplugging devices at boot. We don't need busybox to provide +any other commands in the initramfs because all the rest is done by +skarnet.org binaries. |
