Subject: Initrd problem with 2.6 kernel
Date: Thu, 7 Aug 2003 15:30:19 -0700 [thread overview]
Message-ID: <20030807223019.GA27359@lucon.org> (raw)
There is a chicken and egg problem with initrd on 2.6. When
root=/dev/xxx is passed to kernel, kernel will call try_name, which
uses /sys/block/drive/dev, to find out the device number for ROOT_DEV.
The problem is /sys/block/drive may not exist if the driver is loaded
by /linuxrc in initrd. As the result, /linuxrc can't use
/proc/sys/kernel/real-root-dev to determine the root device number.
H.J.
