3    Runnable Userspace Meta Programs

5Quick rundown of the current directory structure:
6
7sys/rump/librump - kernel runtime emulation
8  /rumpkern - kernel core, e.g. syscall, interrupt and lock support
9  /rumpnet  - networking support and sockets layer
10  /rumpuser - userspace namespace support for previous, *NO* -D_KERNEL
11	      provides e.g. malloc() and some syscalls
12  /rumpvfs  - file system support
13
14sys/rump/include
15  /machine - headers meant to be used for rump compilation when the MD
16	     ones cause too much trouble, e.g. curlwp which is different
17	     from arch to arch
18
19sys/rump/fs - file system rumps
20  /lib/lib${fs}  - kernel file system code compiled out of /sys with -D_KERNEL
21
22sys/rump/net - networking rumps
23  /lib/libnet	  - subroutines from sys/net, e.g. route and if_ethersubr
24  /lib/libnetinet - TCP/IP
25  /lib/libvirtif  - a virtual interface which uses host tap(4) to shovel
26		    packets.  This is used by netinet and if_ethersubr.
27  /lib/libsockin  - implements PF_INET using host kernel sockets.  This is
28		    mutually exclusive with net, netinet and virtif.

31src/lib
32  /libp2k  - puffs-to-vfs adaption layer, userspace namespace
33  /libukfs - user kernel file system, a library to access file system
34	     images (or devices) directly in userspace without going
35	     through a system call and puffs
36
37src/usr.sbin/puffs
38  rump_$fs - userspace file system daemons using the kernel fs code
