параметры конфигурации и монтирования для файловых систем FUSE (configuration and mount options for FUSE file systems)
Безопасность (Security)
The fusermount3 program is installed set-user-gid to fuse. This
is done to allow users from fuse group to mount their own
filesystem implementations. There must however be some
limitations, in order to prevent Bad User from doing nasty
things. Currently those limitations are:
1. The user can only mount on a mountpoint, for which it has
write permission
2. The mountpoint is not a sticky directory which isn't owned
by the user (like /tmp usually is)
3. No other user (including root) can access the contents of
the mounted filesystem.
