/dev/mapper/root is a crypted luks-partition made with "cryptsetup-1.0.6". > Since it was fine just after mounting in init (you already tested), I am > afraid that /dev/mapper/root became unavailable after switch_root. Yes, I agree, there may be something. /dev/mapper/root holds the whole root-tree (/bin, /lib, etc.). With the exception of accessing the "/" and "system/roroot" after the system has fully booted, everything works fine. Therefore /dev/mapper/root should be accessable. But I remember that switch_root of busy-box tries to delete the contents of the old initramfs root. Pherhaps there is a side-effect. I've tried so rescue /dev, /proc and /sys over to the normal system. The symtoms remain the same. Additionally (on a hint in this ML from Vito Tafuni) I've tried Kernel 2.6.27.7 with aufs2-base5. Same effect. Then I decided, to forget the possibilitiy to have access to the branches after boot. I attach the new init (only changed the lines after "# Use aufs for newroot"). Now, if /dev/mapper/root would not be accessible, I should have the same problem. But now my segmentation fault has gone! I only changed the way how directories are mounted. Now the following shows up with 'df -h': ----------- snip ---------------------------------- r...@i686emg:~# df -h Filesystem Size Used Available Use% Mounted on rootfs 220.0M 148.0k 219.9M 0% / df: /roroot: No such file or directory df: /ramroot: No such file or directory none 220.0M 148.0k 219.9M 0% / udev 220.0M 36.0k 220.0M 0% /dev ramdisk 50.0M 168.0k 49.8M 0% /var ----------- snap --------------------------------- Those "No such file or directory" don't look fine, but it works. At the moment I have no further ideas. Siegfried
