Correct some incorrect variables names.
Fix a bad parenthesis.
Remove a check in 'read' method of the 'Remote' object. This check was
checking if the 'path' parameter was a file but it introduce a bug with
Linux chroot. Indeed, 'read' function in 'Linux' object, call the parent
function via the 'super' keywork and the check don't check the path in
the chroot filesystem but in the parent filesystem (call the parent
'isfile' function)! Any function in 'Remote' object called via 'super'
keyword in 'Linux' object should not call internal function of the
object.
Improve 'size' function.
Correct some errors in linux subpackage.
Improve network configuration of Deb based hosts by creating one file per interfaces.
Updating Rpm based object with functions for setting hostname and network configuration.
