## BUGS

- •

  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.

## constructor

## new

parameters are:

- model

  Config::Model object

- root

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

- mountpoint

  ## Methods

### run\_loop

Parameters: `"( 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.

### fuse\_mount

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