[gentoo-catalyst] linuxrc unfindable (by me, not the kernel) / who mounts the loop?

[Isidore Ducasse]

I'm trying to catch what happens on bootup over the livecd, before squashfs 
loop gets mounted. My specfile says that linuxrc is not used by default, the 
gentoo.igz archive on my cd doesn't hold any file (excepted fstab, 
mentionning / and /proc), but grub mentions a /linuxrc and the cd obviously 
starts the default init script on bootup before accessing the squashfs 
loop... Who is mounting the loop anyway?

Since I could not find any linuxrc file on the cd archived or whatever, I 
assume there's a /init living in the kernel's initramfs... and 
grub's "init=/linuxrc" otion applies for initrd root only, so it gets zapped. 
Am I wrong?

But I just can't find the original one... or any copy of it at all! Since I 
don't want to re-invent the wheel, could anyone tell me where to get it?

By the way I couldn't find anything mentioning linuxrc on 
http://www.mail-archive.com/gentoo-catalyst%40lists.gentoo.org/ . Is this 
server hosting all the posts to the list?
