BUGS

For some configuration, mapping each parameter to a file may lead to a high number of files.

constructor

new (...)

parameters are:

model

Config::Model object

root

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

mountpoint

Methods

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, the call will return after forking a process that will perform the mount. Debug parameter is passed to Fuse system to get Fuse traces.

fuse_mount

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