(that's the name from db 2.4.14 which comes with glibc 2.1.x) and
"libdb-3.0.so" (the name used by db 3.0.55 as default).
+The nss_db module is now in a separate package since it requires a database
+library being available.

+?? What has do be done when upgrading to glibc 2.2?
+
+{AJ} The upgrade to glibc 2.2 should run smoothly, there's in general no
+need to recompile programs or libraries. Nevertheless, some changes might
+be needed after upgrading:
+- The utmp daemon has been removed and is not supported by glibc anymore.
+ If it has been in use, it should be switched off.
+- Programs using IPv6 have to be recompiled due to incompatible changes in
+ sockaddr_in6 by the IPv6 working group.
+- The Berkeley db libraries have been removed (for details see ??nssdb).
+- The format of the locale files has changed, all locales should be
+ regenerated with localedef. All statically linked applications which use
+ i18n should be recompiled, otherwise they'll not be localized.
+- glibc comes with a number of new applications. For example ldconfig has
+ been implemented for glibc, the libc5 version of ldconfig is not needed
+ anymore.
+- There's no more K&R compatibility in the glibc headers. The GNU C library
+ requires a C compiler that handles especially prototypes correctly.
+
+Please read also the NEWS file which is the authoritative source for this
+and gives more details for some topics.
