[Trisquel-users] Re : New user - root password problems

[lcerf]

As I already wrote: there is no security when the attacker has a physical  
access to the hardware. He can read the disk in a variety of ways... as long  
as the data are unencrypted. Automatic login and an absence of locking after  
inactivity make no
difference for a remote attack. As a consequence, they do not really weaken  
the security.

They are psychological incentives for your co-workers or your family not to  
look at your data/activities when you are AFK (a little more effort is  
required: burning a live system on a USB drive for instance).
