    Runnable Userspace Meta Programs

Quick rundown of the current directory structure:

sys/rump/librump - kernel runtime emulation
  /rumpkern - portion compiled with -D_KERNEL, uses kernel headers
  /rumpuser - userspace namespace support for previous, *NO* -D_KERNEL
	      provides e.g. malloc() and some syscalls

sys/rump/include
  /machine - headers meant to be used for rump compilation when the MD
	     ones cause too much trouble, e.g. curlwp which is different
	     from arch to arch

sys/rump/fs - file system rumps
  /lib/lib_$fs  - kernel file system code compiled out of /sys with -D_KERNEL


Users:
src/lib
  /libp2k  - puffs-to-vfs adaption layer, userspace namespace
  /libukfs - user kernel file system, a library to access file system
	     images (or devices) directly in userspace without going
	     through a system call and puffs

src/usr.sbin/puffs
  rump_$fs - userspace file system daemons using the kernel fs code
