Now, lidsadm commands won't ask you for a password anymore when they are launched from this shell or a child of its.
Moreover, each time you request an overload without the -a option, the overload will be linked to the LFS used, so that when the shell dies or when the LFS is closed, every overload done in this session and inherited from overloads linked to this session will disappear.
You can make an overload linked to your LFS only if the process also is in your LFS, ie have the same LFS master as your command. There is a command to adopt a process into a LFS, and one do delete his link to the LFS.
There can be as many opened session as you want, which can be closed only by a process of the session, or by a timer created by a process of the session.
A process cannot have more than one LFS master.
