This is used by netinet and if_ethersubr. 28 /lib/libsockin - implements PF_INET using host kernel sockets. This is 29 mutually exclusive with net, netinet and virtif. 30 31Users: 32src/lib 33 /libp2k - puffs-to-vfs adaption layer, userspace namespace 34 /libukfs - user kernel file system, a library to access file system 35 images (or devices) directly in userspace without going 36 through a system call and puffs 37 38src/usr.sbin/puffs 39 rump_$fs - userspace file system daemons using the kernel fs code 40
