This module provides a virtual file system interface for you configuration data. Each possible parameter of your configuration file is mapped to a file.


 $ cme fusefs popcon -fuse-dir fused
 Mounting config on fused in background.
 Use command 'fusermount -u fused' to unmount

  • For some configuration, mapping each parameter to a file may lead to a high number of files.
  • The content of a file is when writing a wrong value. I.e. the files is empty and the old value is lost.


new (...)

parameters are:
Config::Model object
Root of the configuration tree ("Config::Model::Node" object )


run_loop( fork_in_loop => 1|0, debug => 1|0)

Mount the file system either in the current process or fork a new process before mounting the file system. In the former case, the call is blocking. In the latter case, the call returns after forking a process that performs the mount. Debug parameter is passed to Fuse system to get traces from Fuse.


Mount the fuse file system. This method blocks until the file system is unmounted (with "fusermount -u mount_point" command)
