Bug#787554: initramfs-tools: failed to start /dev/mdx, Usage: readlink, Can't find /root in /etc/fstab
Package: initramfs-tools
Version: 0.120
Severity: important
Hi
I have some problems booting with initrd, it doesn't look linke other
bug reports I saw, so here my bug report ... :-)
Screenshot: http://jochen.hin.de/diverses/initramfs-tools-bug.jpg
First the kernel has already startet /dev/md2 and /dev/md3 on my system.
So could I ignore the messages which try to "Assemblling MD array"?
Then there seems to be a problem with a readlink-call:
"Usage: readlink ..."
Then it says "Can't find /root in /etc/fstab"
After than I am stuck in BusyBox.
The Raid is already startet, the Root FS is /dev/md2 and ready to mount.
The /usr FS is on a LVM (on /dev/md3) which is not started yet.
I could manualy mount the Root FS and the /usr FS, also /dev, /proc,
/sys (to /root) but I don't know how to initiate the init from there.
(chroot and start the "real" init)
So I now use my old initrd and my old kernel (2.6.32) to boot my system.
(from Wheezy/oldstable)
Could you help please?
Jochen
