This is used by netinet and if_ethersubr. 33 /lib/libsockin - implements PF_INET using host kernel sockets. This is 34 mutually exclusive with net, netinet and virtif. 35 36Users: 37src/lib 38 /libp2k - puffs-to-vfs adaption layer, userspace namespace 39 /libukfs - user kernel file system, a library to access file system 40 images (or devices) directly in userspace without going 41 through a system call and puffs 42 43src/usr.sbin/puffs 44 rump_$fs - userspace file system daemons using the kernel fs code 45
