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)
