History
pooka 4f69d01d2f Add the ability to run puffs in userspace. This means that puffs 
can now be developed in userspace using puffs for development
(I hate emulators, they are annoyingly clumsy).

To e.g. mount psshfs using puffs-on-puffs, run fs/bin/syspuffs/syspuffs
with the regular mount_psshfs command line as an argument:

    golem> ./syspuffs /usr/sbin/mount_psshfs ftp.netbsd.org:/pub /puffs

This will make the mount appear as usual, with the exception that the
requests will be passed through puffs both in the kernel and userspace:

    ftp.netbsd.org:/pub on /puffs type puffs|p2k|puffs|psshfs

    Runnable Userspace Meta Programs

Quick rundown of the current directory structure:

/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

/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

/fs - file system rumps
  /lib - libraries used by fs rumps
    /lib$fs  - kernel file system code compiled out of /sys with -D_KERNEL
    /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
  /bin - rumps themselves.  fsconsole uses ukfs directly.  the rest are
	 file system specific rumps and use puffs
