+ libp2k: the interface between libpuffs and vfs/vop
+ libukfs: generic user kernel file system library, usable
independent of libp2k and/or puffs
* use file system name (MOUNT_XYZ) instead of vfsops pointer to
mount file system
any real trickery. Unfortunately this was the easy part; r/w
support is going to make ascending naked, blind, illiterate, without
food and as an atheist look trivial.
/sys/rump contains programs which run unmodified kernel code in an
emulated userspace environment. The kernel environment is provided
by librump. Currently supported are a number of file systems,
which by using puffs integrate seamlessly into the system and
provide a similar user experience to if the code was running as
part of the kernel. Potential future rumpification targets include
for example parts of the networking stack and some device drivers.
