Due to the experimental nature of the current book, the host must be
-running at least a 2.6.2 kernel. The reasons for this high
-requirement is the use of NPTL, but more importantly the use of udev. Udev
-creates devices dynamically by reading from the sysfs file system. Only very
+running at least a 2.6.2 kernel compiled with gcc-3.0 or
+higher. There are two main reasons for the high requirement. Firstly, we make
+use of the Native Posix Threading Library (NPTL) whose testsuite will segfault
+if the host's kernel hasn't been compiled with gcc-3.0 or later. Secondly, the
+2.6.2 or later version of the kernel is required for the use of udev. Udev
+creates devices dynamically by reading from the
+sysfs file system. Only very
recently has support for this file system been implemented in most of the kernel
drivers, however. We must be sure that all the critical system devices get
created properly.
