+Our current recommendation is to use Inferno (http://www.vitanuova.com/inferno)

+have to choose a higher port number if running as a normal user).  The '#U*'

+       help
+        This is needed when the host kernel on which you run has a non-default
+       (like 2G/2G) memory split, instead of the customary 3G/1G. If you did
+       not recompile your own kernel but use the default distro's one, you can
+       safely accept the "Default split" option.
+
+       It can be enabled on recent (>=2.6.16-rc2) vanilla kernels via
+       CONFIG_VM_SPLIT_*, or on previous kernels with special patches (-ck
+       patchset by Con Kolivas, or other ones) - option names match closely the
+       host CONFIG_VM_SPLIT_* ones.
+
+       A lower setting (where 1G/3G is lowest and 3G/1G is higher) will
+       tolerate even more "normal" host kernels, but an higher setting will be
+       stricter.
+
+       So, if you do not know what to do here, say 'Default split'.
