Subject: determine boot device in initrd
Date: Thu, 20 Jan 2011 11:57:59 +0200 [thread overview]
Message-ID: <A4B10BB8CE8F86468ABF12A5E4A5CC9920F919A3C4@mail> (raw)
Hi,
I have a system with several USB disks, each of them is boot-capable.
Each such device has a kernel and initrd in its filesystem.
I want to be able to determine in initrd from which USB device it (and the kernel) were
loaded from, so I can mount the root filesystem from that device.
Is that doable?
I don't want to use a static "root=" entry in grub, since I don't know which sd device it will be.
Thanks,
Jacob Avraham
