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 question 2.31). • 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.
