+2.20.	Even statically linked programs need some shared libraries

+
+{AJ} NSS (for details just type `info libc "Name Service Switch"')
+won't work properly without shared libraries.  NSS allows using
+different services (e.g. NIS, files, db, hesiod) by just changing one
+configuration file (/etc/nsswitch.conf) without relinking any
+programs.  The only disadvantage is that now static libraries need to
+access shared libraries.  This is handled transparently by the GNU C
+library.
+
+A solution is to configure glibc with --enable-static-nss.  In this
+case you can create a static binary that will use only the services
+dns and files (change /etc/nsswitch.conf for this).  You need
+to link explicitly against all these services. For example:
+
+  gcc -static test-netdb.c -o test-netdb.c \
+    -lc -lnss_files -lnss_dns -lresolv
+
+The problem with this approach is that you've got to link every static
+program that uses NSS routines with all those libraries.
+
+{UD} In fact, one cannot say anymore that a libc compiled with this
+option is using NSS.  There is no switch anymore.  Therefore it is
+*highly* recommended *not* to use --enable-static-nss since this makes
+the behaviour of the programs on the system inconsistent.

+4.3.	When I set the timezone I'm by setting the TZ environment variable

+
+{UD} The problem is that people still use the braindamaged POSIX
+method to select the timezone using the TZ environment variable with a
+format EST5EDT or whatever.  People, read the POSIX standard, the
+implemented behaviour is correct!  What you see is in fact the result
+of the decisions made while POSIX.1 was created.  We've only
+implemented the handling of TZ this way to be POSIX compliant.  It is
+not really meant to be used.
+
+The alternative approach to handle timezones which is implemented is
+the correct one to use: use the timezone database.  This avoids all
+the problems the POSIX method has plus it is much easier to use.
+Simply run the tzselect shell script, answer the question and use the
+name printed in the end by making a symlink to
+/usr/share/zoneinfo/NAME (NAME is the returned value from tzselect)
+from the file /etc/localtime.  That's all.  You never again have to
+worry.
+
+So, please avoid sending bug reports about time related problems if
+you use the POSIX method and you have not verified something is really
+broken by reading the POSIX standards.
