The choice of shared library versions from util-linux-ng-2.16-rc2:
 	libblkid.so.1 -> libblkid.so.1.0.0
 	libuuid.so.1 -> libuuid.so.1.0.0
is somewhat unfortunate, because e2fsprogs-1.41.3 has:
 	libblkid.so.1 -> libblkid.so.1.0
 	libuuid.so.1 -> libuuid.so.1.2
with the consequence that as long as the older e2fsprogs libraries are not
removed, ldconfig will create a symlink to the older libuuid from e2fsprogs
(I am not sure about the symlink for libblkid).

This problem could safely be avoided if util-linux-ng were to choose at
least libuuid.so.1.2.0 or maybe even better to be absolutely safe
libblkid.so.1.1.0 and libuuid.so.1.3.0.

Peter
