Description Gilles Detillieux 2008-05-28 16:39:57 EDT
Description of problem:
The dhcpv6-1.0.17-1.fc10.src.rpm package, or more specifically subpackage
libdhcp6client-1.0.17-1.fc10.i386.rpm, breaks nash, and therefore mkinitrd,
because it drops the symbol dadlist which nash needs.  (nash is from

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. run "yum update" on a rawhide system to load up
2. run "/sbin/mkinitrd --allow-missing -f
/boot/initrd-2.6.26-0.37.rc4.fc10.i686.img 2.6.26-0.37.rc4.fc10.i686" or just
try upgrading a kernel through yum or rpm.
3. ls -l /boot/initrd-2.6.26-0.37.rc4.fc10.i686.img
Actual results:
/sbin/nash: symbol lookup error: /usr/lib/libdhcp6client-1.0.so.2: undefined
symbol: dadlist
(repeated 37 times)
and /boot/initrd-2.6.26-0.37.rc4.fc10.i686.img is only 50 bytes.

Expected results:
mkinitrd runs silently and makes an initrd of ~2.8 MB.

Additional info:
This is remarkably similar to bug 435636 from March 2, where
libdhcp6client-1.0.12 dropped the dhcpv6_client symbol.  Is someone a bit
overzealous in purging out "obsolete" parts from this library?  nash/mkinitrd
was updated only 3 weeks ago, so it's not exactly old cruft.
Comment 1 David Cantrell 2008-05-28 17:00:11 EDT
Just fixed in rawhide.

Yes, I am actively trying to get rid of this library (libdhcp6client) because it's horrible.  Over the weekend I 
removed the homegrown netlink code and have it using libnl instead.  I moved the dadlist variable by 
mistake, apologies.
