-// README

-// What is this?
-//
-// sdcard is a program that uses FUSE to emulate FAT-on-sdcard style
-// directory permissions (all files are given fixed owner, group, and
-// permissions at creation, owner, group, and permissions are not
-// changeable, symlinks and hardlinks are not createable, etc.
-//
-// See usage() for command line options.
-//
-// It must be run as root, but will drop to requested UID/GID as soon as it
-// mounts a filesystem. It will refuse to run if requested UID/GID are zero.
-//
-// Things I believe to be true:
-//
-// - ops that return a fuse_entry (LOOKUP, MKNOD, MKDIR, LINK, SYMLINK,
-// CREAT) must bump that node's refcount
-// - don't forget that FORGET can forget multiple references (req->nlookup)
-// - if an op that returns a fuse_entry fails writing the reply to the
-// kernel, you must rollback the refcount to reflect the reference the
-// kernel did not actually acquire
-//
-// This daemon can also derive custom filesystem permissions based on directory
-// structure when requested. These custom permissions support several features:
-//
-// - Apps can access their own files in /Android/data/com.example/ without
-// requiring any additional GIDs.
-// - Separate permissions for protecting directories like Pictures and Music.
-// - Multi-user separation on the same physical device.
