Bug 491778 – sys-kernel/dracut-034-r1 - when booting a thin rootfs - multiple errors '/sbin/thin_check: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory'

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Norman Back 2013-11-20 15:19:48 UTC]

When booting a thin rootfs via an initrd created with sys-kernel/dracut-034-r1 multiple shared library errors are displayed. These errors do not occur when using an initrd created with sys-kernel/dracut-027-r3

From /var/log/rc.log

Boot then appears to complete normally.


Reproducible: Always

Steps to Reproduce:
1. boot a thin provisioned rootfs via an initrd created with sys-kernel/dracut-034-r1
2.
3.
Actual Results:  
 * Starting dmeventd ...
 [ ok ]
 * Setting up the Logical Volume Manager ...
/sbin/thin_check: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

thin_check appears to work OK when invoked manually

but libstdc++.so.6 is on mount point /usr , which was mounted by dracut.

I suspect this is a dublicate of bug 489624

I'm not so sure. On my system /usr is mounted by initramfs.

If you haven't explicitly enabled usrmount module, then it is 100% not included in initramfs. Please try the patch attached to bug 489624.
