From bca1033b092a6fab2ed00036e8a7f6e2df5d99a2 Mon Sep 17 00:00:00 2001 From: Marton Balint Date: Tue, 6 Jan 2009 14:40:43 -0800 Subject: do_mounts: add device info to mount message In the past, I used the root=... command line parameter to specify the root filesystem to the kernel. Now it seems that specifying it is not necessary. The kernel detects the root filesystem even if the kernel command line is empty. My root fs is on a raid1 device by the way, and I am not using initrd for the boot process. If the kernel detects the root filesystem somehow, I think it should print out the result of this detection, otherwise I will not know which device has the root filesystem. Or is there an easy way to get this information on a running system? I had a quick look at the /proc and /sys filesystems, but haven't found anything useful there.
