asta face automount-ul, monteaza cand intri in directorul respectiv.

din man poweroff:
If you're not the superuser, you will get the message
`must be superuser'.
din man shutdown:
ACCESS CONTROL
shutdown can be called from init(8) when the magic keys
CTRL-ALT-DEL are pressed, by creating an appropriate entry
in /etc/inittab. This means that everyone who has physical
access to the console keyboard can shut the system down.
To prevent this, shutdown can check to see if an autho�
rized user is logged in on one of the virtual consoles. If
shutdown is called with the -a argument (add this to the
invocation of shutdown in /etc/inittab), it checks to see
if the file /etc/shutdown.allow is present. It then com�
pares the login names in that file with the list of people
that are logged in on a virtual console (from
/var/run/utmp). Only if one of those authorized users or
root is logged in, it will proceed. Otherwise it will
write the message
shutdown: no authorized users logged in
to the (physical) system console. The format of /etc/shut�
down.allow is one user name per line. Empty lines and com�
ment lines (prefixed by a #) are allowed. Currently there
is a limit of 32 users in this file.
