What part of initramfs (Ubuntu) runs scripts/local?

Question

I'm trying to understand how Ubuntu 12.04's initramfs runs scripts/local and in what order. I don't see it in init. What line of code runs scripts/local?

Answer 1

scripts/local is only run when using a local root filesystem (as opposed to a network filesystem). The BOOT variable in the init script is set to either local or nfs accordingly, so the following line sources scripts/local:

$ grep -A1 Mounting init
log_begin_msg "Mounting root file system"
. /scripts/${BOOT}
