The user-mode port of 2.4.4 is available.
The swap problems that were in the 2.4.3 UML are fixed.
It is now possible to attach already-running debuggers and debuggers other
than gdb to UML. See http://user-mode-linux.sourceforge.net/debugging.html
for details. There, I give an example of using strace as an alternate
debugger.
gprof and gcov support now work again. They can be enabled during
configuration under the 'Kernel Hacking' menu.
UML can boot from an initrd image. This done with 'initrd=<image>' on the
command line.
I fixed a long-standing race which caused sleep to hang.
