This file is part of the CernVM File System.
Implements stub callback functions for Fuse. Their purpose is to redirect calls to the cvmfs shared library and to block calls during the update of the library.
The main executable and the cvmfs shared library must not share any symbols.instead of including attr/xattr.h

Users create derived instances to react on repository diffs
Depending on the desired course of action, the permitted capabilities of the binary (cap_dac_read_search, cap_sys_admin) needs to be dropped or gained. Dropped for creating user namespaces in enter, gained for walking through overlayfs.
If in an ephemeral writable shell, return the session directory. Otherwise return the empty string.
